Framework: Fix derp

Change-Id: I2e5f15675385a1863b3da7fa4ef80f3a605d2470
HOVER: Theme Engine compatibilities and some resources tweaks
Use default notification dimens, avoid setting a custom one.
A bit of cleanup too.

Notifications:
Hardcode dimensions to android defaults. Avoid themes to change them,
Ribbons feature (present on CM based roms mostly) needs that.

Thanks to +John Xionidis to help me trick this out for full CM11 made themes :)
