Patchset 1:
- Switched to static methods and enums
- Moved Navbar helpers to its own class to
  be moved to FW for RC navbar recode.
- Created broadcast reicever
  use it like this...

     Intent i = new Intent();
     i.setAction("com.android.systemui.aokp.LAUNCH_ACTION");
     i.putExtra("action", "**string you want AwesomeAction to
launch**");
     mContext.sendBroadcast(i);

Removed screenshot option for 2 reasons
1) Security
2) Can't be made static.
