Customized - Allow User select Tablet Mode [1/2]

Phone - Traditional separate NavBar/Statusbar
Tablet - Traditional combined SystemBar
Phablet - Phone layout but NavBar stays at bottom.
	  This appears to be what Google is now pushing as
	  The standard Tablet layout.  I don't like it,
	  So I want the option to use Tablet mode above.

Patch6 : fix "Rebase"
