Merge URL bar and tabs toolbar v2.0

/*Version 2 changelog:
Changed the method of disabling the urlbar in fullscreen mode
Todo: Add an option to reset the url bar to a normal non-merged state instead of hiding it
If elements look out of place on your setup, search this CSS for "margin-left" on lines 13 and 42, and edit line 25 if you want to resize the URL bar.
