Small code cleanup. If statement was removed because at this point 'mav' has already been assumed to be non-null for a while.
Fixed warning comparing ints of different signed-ness. Everything should just be unsigned here.
Set most UI to disabled by default with it only enabled on the addition of an active UAS. Added all missing parameter control buttons to the Vehicle Config widget.
Removed extraneous debug statement that just cluttered the console. Hard to debug anything else with this active.
Accidently disabled one of the config panes by default; restoring it.
