mGerrit Changes (Layout + Formatting)

Mostly just formatting and layout stuff, although I did move the
explanation of the Statuses out of Preferences and into a Help dialog
(seemed more fitting). I'm thinking moving the Open Source Libraries
out into an About dialog and then having the Gerrit Instance preference
in a dialog might be good as well, thus eliminating the need for the
Prefs activity.

PS3: Whitespace and tab-->space fixes ( <3 Jonathan ) + fix a compile error
	in xml
PS4: Missed a few...

PS5: Wow I'm bad at this...my thoughts and prayers are with your inboxes

PS6: Color changes! Everything looks a lot more uniformed now

PS7: Pretty sure I've banished all harcoded colors to the Nether... And some
	minor layout issues

PS8: Dead code can now RIP...more tabs-->spaces fixes

PS9: More tabs-->spaces that I missed
