Create switch for the translucent decor (1/2)

  - this enables the transparent statusbar/navbar on the home screen.

PatchSet 2:
  - fixed the fact that if the frameworks base bool was true nothing would
    happen.
  - in doing it this way the frameworks base bool really don't do anything
    but I'm keeping it just for the default.

PatchSet 3:
  - Set a default setting in the settings provider that can be overlayed
    per device since the setting isn't set on a factory reset till its
    checked
