Callbacks are not notified when the wallpaper is changed to
a live wallpaper.  This patch notifies callbacks of the change
regardless of the type of wallpaper be set.

CM11 Themes: Clear wallpaper mixnmatch entry on external change

If a wallpaper is applied from a theme and the wallpaper is changed
from an external source, the theme is still shown to have its
wallpaper applied.  This patch will clear this value out when a
wallpaper change is detected that is not from the ThemeService.

SignalStrength: Hotfix TD-SCDMA take 2
