GCS InputWizard: do not change FlightStatus to period

There is no need to set FlightStatus to periodic. OnChange
is more reliable for things that rarely change. Just need to
make sure the other objects don't clobber FlightStatus when
that is needed.
GCS Input Wizard: remove old logo from transmitter
GCS Failsafe Configuration: disable fast updates of other objects

These fast updates clobbered the ones we wanted
GCS Input Wizard: transparent background around transmitter

No need for the gray background. This looks cleaner.
