Realized that I had configured my APM:Plane incorrectly since
FlightModeConfig was only set up to work with APM:Copter. Changed code
to respect mode switch channel parameter across all APM frame types.
Also a pile of other changes to make this code much more bullet proof
and correct. Implemented simple mode as well. Changed the style of the
code to be more data driven. This allows for adjusting for new param
values without needed to changing any code.

Fix for accelerometer config failure leading to inability to recalibrate. Also changing screen will void calibration and require recalibration.

Change so firmware information requests happen 10 seconds after startup instead of 0.5seconds, to avoid a race condition

Fix for potential race condition where UI is not finished configuring when parameters start coming in

Changes for AdvParameterList number display, and proper handling of CH6/7/8 options in ArduCopter pids
