Fixed up everything.  Please never, ever use configChange.  #1 advice to all Android devs.

Also, note the new color in the navigation drawer.  Oooh, aaah.
I understand, but since it is an UI element, I would rather delegate this responsability to the fragment or the activity.
The best choice is, for me, firing an event, so any interested element can do what it want with it (see branch androidL).
