RC: Overhaul NavBar buttons UI
I decided to make some pretty heavy changes to the
resource allocation as well (using AwesomeAction/Constants).
Still need to move over the icons.  This will also require
modifying SystemUI to use the same sources.
ToDo:  Custom Icons part not working.
This allows **ALL** actions from AwesomeConstants. We need to
either make sure SystemUI can handle all of these actions, or
figure out a way to make it easy to filter out which ones we
don't want for the NavBar.
PS2:  Hopefully fixed the shortcut/app & icon pickers
(still compiling - haven't tested it yet)
Also moved icon resources over to frameworks and now getting
them from AwesomeConstant.
ps3:  Trying to make the NavBar Preview respect certain color
settings (NavBar Color, NavButton Color, etc).  Having limited
success so far.  Need to dig deeper.  Also, custom icons not
working quite yet.
ps4:  Realigned Preferences so that NavBar buttons is at the top
of the listview.
todo: Figure out why custome icons doesn't work.
ps5:  Couple of more visual tweaks
ps 6: Abandon the custom pref idea and re-integrate into NavBar.
Not sure if this works, but I need to rebase ... so pushing.
ps 7: Re-integrated back into NavBar preference.  Now inflates
custom layout so that NavBar UI stays at top of list and other
options scroll underneath.  I would like for the NavBar UI to
fully reflect other options (colors, menu layout, etc).  I'm
getting some of this to work, but background color and Alpha are
not working.
However, this is fully functional at this point.
ps 8: Fixed colors and alphas
ps 9: Fixed glow by using a state drawable instead of on touch listener.
      needs the glow alpha to get fixed what I have doesnt do anything...
ps 10:  fix background to be the full width (not just buttons).
	All other visual cues appear to be reflecting properly in
	the UI.  Moved the options around to be more consistent
	and set certain options to remove depending on UI mode.
ps 11: Fix preference derp and remove whitespace
Settings: appwidgetloader...load all providers to do a proper filter
google fixed up the keyguard code in frameworks but did not
adjust in settings the widget filter for it. At least if google
would be consisten they can completly get rid of the filter methods
in settings due that they bypass already the right filter for fetching the
provider now (4.2.2 that was broken). Whatever we do not want
to get rid of it due that we have the show all widgets button
on lockscreen which needs a filtering dependend if the user
pressed the button or not. So fetch all widget providers and
let proper work googles forgoten code
