ROMControl: Customizable Softkeys

This allows enabling, and setting of sort and long press options
for softkeys.

Overlay will enable this section as well as let RC know which buttons
the device has.

for testing the section is enabled and so are home, menu, search, and back

If your device doesnt have those buttons just ignore them for now your
users will never see them.

PS2: Add missing drawables
PS3: Fix compile
PS4: Fix RNF Exception (strings didnt forward port)
PS5: Remove Longpress to Kill in UI Settings
PS6: Forgot git add :P

PS7: get actions from frameworks helpers.
