QuickSettings: Added ProfileTile [2/2]

see frameworks commit for details

Patchset 2:
  using blunden's png resource
  making ProfileSettings reachable from the outside

Patchset 3:
  The profile tile should not be available if profiles are turned off

Side rant: I really hate manifest cleanups. i would wish for our
settings not beeing such a mess and comply with fragments properly.
