UI Changes 

1. Made more space for links hover in statusbar - Moved Progress Bar below addressbar.
    a) Thinly visible when loading, hides when loaded.
    b) No flickering as progress bar and browser share same row.
2. Behaviour to load page when hit Enter in Addressbar - Behaviour for that.
2. Refactor.
