Fix bug #13140648 Settings needs to support the new Quantum Paper theme

Second pass:

- use Theme Holo for the Drawer too
- add a temporary background for Drawer icons (so that they dont mix
with the Drawer background)
- remove the "More..." icon as it was not needed

This CL will show that there is a discrepancy into the Drawer icons
size (some are smaller than the standard size, some other bigger).

This issue will be fixed when the new set of Icons will be delivered
by the UX team.
