Quicksettings: full qs rewrite

partially based on the CM style qs without the user configurable backend
for now, just the basics...

adding the follwing static tiles:
  User
  Settings
  Sound
  Gps

also adding the following dynamic tiles:
  Alarm
  Bug Report
  Wifi Display
  Ime switcher
Quicksettings: a Gps tile really isn't even needed...
