Subject: Move navigation bar to bottom
Adds an accessibility flag that allows navigation bar to be moved to the bottom.
Unlike what is present in other browsers, this actually moves the bar below,
without creating other elements.
The bottom bar will also be colored as the navigation bar to make the interface
more pleasant and fixes upstream bug 1285311.
Support for tablet mode is also included.
