fb: Mighty new Power Menu (1/2)

So currently:
airplanemode
custom apps
screenshot
reboot
sound
power off

are available as options to add or remove or customize with our
easy dslv settings

As well we are only using our central classes for it....means adding
whatever shortcut is mostly only a 10 line change in future
