Customizable Softkeys: ROMControl Part

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.

Add Header Icons.

Add double click options.

Using arrays here to reduce signature in Settings.System and PWM

set configs to false, overlay needed to use this feature now.
