SysUI:  NavBar & Widgets rollup [1/2][WIP]

This will bring back NavBar widgets, along with some
changes/rollups on the NavBar side.
Very much a WIP. Just wanted to post where I was so others
could continue if I get busy.

2 :  Address some Tablet stuff
3 :  Icons & Strings
4 :  another icon
5 :  more icons & layouts
6 :  fix some shortcut/aokp action stuff- fix NavRing so it
     only inflates on swipe, not long press of home.
7 :  Roll in jubakuba's porting of Hide NavBar.  Really needed to
     be handled in this mega-NavBar commit rather than separately.
8 :  API change fix for setInitialDisplaySize
9 :  restore Searchlight (NavRing on lockscreen) that got removed
     during the previous edits.
10 : move togle classes under aokp package
11 : Fix reference in Phablet NavBar layout
