* Display date difference in days if can't display in days/weeks/months/...
* add comments
* remove not used variable totalDaysDiff
* improve UpdateDisplayResult
* Display error message when the calculator can't calculate the difference between 2 dates
The incrementally calling `Window::Globalization::Calendar::AddMonths`
resulted in a negative value for `GetDifferenceInDays` which was then
assigned to an unsigned variable `daysDiff`.
One example of the issue when running the calculator in UTC+2 was the
difference between July 31st and December 30th.
The initial guess was 4 months which then landed on November 30th.
This date was stored and then in the loop incremeted by one month.
This then landed precisely on the end date December 30th.
After the loop the final value is then used July 31st + 5 months
which results in the 31st of December.
The resulting difference of -1 days is then assigned to the unsigned
value `daysDiff`.
This commit makes the minimal changes to remedy this bug.
It makes sure to only ever call `AddMonths` with the same starting date
instead of incrementally to different dates.

This is extract from #211 that enables compilation with GCC. With #211
now in the state of bitrot, I would rather try approaching it in smaller
steps that can be hopefully merged quicker, even if it does not provide
full support for all the features #211 provided.
This will _compile_ correctly with my (@janisozaur) GCC, but clang is
more picky about flexible array members and refuses to compile it yet.
I will extract remaining parts of #211 in future PRs.
I marked @fwcd as author, as he did most of the work in #211.
We are migrating the REST endpoint that Currency Converter uses. The REST endpoint is not licensed for your use. To continue to enable community participation in the development of the feature, developer builds will use an alternate REST endpoint that serves mock data (clearly identifiable as it references planets instead of countries).
* Force en-US for unit tests
* fix some spacing issues after merge
* remove default argument of LocalizationService to fix compilation issue in Release mode
Verify if the StandardCalculatorViewModel::DisplayValue isn't an error message before removing group separators (including space character).

This PR fixes code style for the project files.
The Problem
Different files in the project use different code style. That is not consistent and leads to harder maintenance of the project.
Description of the changes:
Have investigated and determined the most used code style across the given codebase
Have configured IDE and applied code style to all project files.
Have crafted clang-formatter config.
see https://clang.llvm.org/docs/ClangFormat.htmlhttps://clang.llvm.org/docs/ClangFormatStyleOptions.html
Some cases were fixed manually
How changes were validated:
manual/ad-hoc testing, automated testing
All tests pass as before because these are only code style changes.
Additional
Please review, and let me know if I have any mistake in the code style. In case of any mistake, I will change the configuration and re-apply it to the project.

Divide by 4 the CPU usage of OverflowTextBlock when buttons are pressed very quickly.
Description of the changes:
Xaml-side:
OverflowTextBlock has some performance issues:
double scrollviewer: the listview was in a scrollviewer, while the control already containing one -> it breaks the virtualization of the listview and impacts on UI performance.
The listview used a StackPanel, this panel doesn't support virtualization of ListViewItems contrary to ItemsStackPanel
No ListView-specific features were used, an ItemsControl is more efficient and lighter.
refactor how we manage the visibility of the left/right buttons in OverflowTextBlock, the new version is more reactive and will not display the right arrow when not necessary (see GIF below).
remove the ItemContainerSelector ExpressionItemContainerStyle, not really used by OverflowTextBlock
remove UI glitches generated by ChangeView when users type fast (control partially hidden and scrolling issues, see the GIF below).
only modify the accessibility view when it's necessary
ViewModel-side:
stop fully refreshing ExpressionTokens in StandardCalculatorViewModel when a new command were sent, instead, use a IObservableVector to only send new tokens to the UI (in average only 1 or 2 UI items are refreshed while the full expression was refreshed before)

Add Pyeong as an Area conversion unit.
Pyeong shows up only if the user's current region is Korea ( i.e. region is either KP or KR ).
Added Korean translation for Pyeong (평). For other locales, we default to English ( Pyeong ).

Manually tested the below
For non-Korean regions, Pyeong does not show up.
Korean region with Korean locale => Pyeong shows up and Pyeong is correctly translated.
pyeong_Korean
Korean region with English locale => Pyeong shows up and Pyeong is in English.
pyeong_English
Korean region with simplified Chinese locale => Pyeong shows up and Pyeong is in English.

Description of the changes:
prevent UnitConverterViewModel to reset values when users click on update rates.
recompute UnitConverter's caches (m_ratioMap and m_categoryToUnits) once rates are updated (but check first if the user did/didn't change the category)

Manually tested with fake currency rates (HTTP responses modified on the fly via FiddlerCore)
Verified that it works no matter the selected field (From or To)
Verified that the currencies selected are kept after a refresh
Description of the changes:
Currently Calculator handles strings by defining integers for each type of function that can be performed, this integer will eventually correspond with an index in s_engineStrings which holds the corresponding display string for each function. Some functions such as Sin can have multiple strings (degrees, rads, grads, inverse). Functions like Sin are mapped to another array called "rgUfne" where a new integer is given depending on the output string which will then be given to s_engineStrings. The new integer returned by the "rgUfne" array runs the risk of overlapping with any new functions that may be added in CCommand.h. Furthermore, it is expected that the strings in s_engineStrings and rgUfne are defined in a particular order (not necessarily sequential), otherwise the logic will break. This makes adding new strings for new functions confusing and difficult, since a lot of the logic is not clearly defined.
This PR attempts to make this a bit simpler by changing the s_engineStrings and rgUfne arrays to be unordered_maps instead of arrays. For s_engineStrings the keys will now be strings, allowing the existing logic for indexing to be used by simply converting the number into a string to access the value. This will also allow us to create keys in the future that are not limited to integers but to strings that hold more meaning.
The rgUfne array will also be updated to be a map that will take in an integer and give you the corresponding string that can be passed to s_engineStrings. The UFNE object in the rgUfne array will also be updated to hold all the possible string keys for a function, instead of indexing them on other numbers that may overlap with existing definitions.
Now to add a new string for a new IDC_FOO function, we would just need to add the "FooString" resource keys to the g_sids array and use the updated rgUfne map to link the IDC_FOO value to the corresponding "FooString" resource key. This way the resource key can be a meaningful string, and not an integer that must be in any particular order.

The ViewModel wrongly assumed that non-breaking spaces were only used between the value and the symbol. It's not the case of all locales using non-breaking spaces as a thousand delimiter (French for example).
When it was the case, the function only replaced the first thousand delimiter found and kept the extra space at the end of the string, generating 2 issues:
Extra space at the end: #240
Bad formatting of the number: #232
Description of the changes:
Replace currencyResult.find(L'\u00a0') by a regex only removing spaces at the end of the string.
Fixes#240 and #232
The application uses local time to calculate the number of days between 2 dates. If a Daylight Saving Time takes place during this period of time (only Clocks Forward 2am->3am), the application will miss 1 day and fail to calculate the number of days/weeks/months between the 2 dates.

Description of the changes:
DateCalculationEngine uses local time to modify dates, however, AddDays, AddWeeks,... won't add 24 hours or 7 days if DST happens between the 2 dates, but instead add ~23.9/24.1 hours or ~6.9/7.1 days (depends if it's the DST clock backward or clock forward). When the DST is clock forward, DateCalculationEngine will miss one day.
Solution
use UTC dates to calculate date difference.
Extra Fix:
use calendar->FirstPeriodInThisDay and calendar->FirstHourInThisPeriod in ClipTime (else it will set the time to 12PM (noon) in some regions.
replace OBSERVABLE_PROPERTY_RW by OBSERVABLE_PROPERTY_R when possible.
remove the definition of CheckClipTimeSameDay (implementation missing)
