Mms: Add native heads up support

Add heads up support (optional but enabled by default).

Shows important messages of this app as heads up.

Means:
- All MMS
- SMS if quickpopup is disabled

Other messages like storage or blacklist notifications are not important and will not show as heads up

PS:
- show always as expanded.....so user can directly interact with it
