many thanks to Sam Tabor for finding this bug!

the EKF does not estimate wind without an airspeed sensor

this is used to test calibrate the compass, and to test tracking PIDs

allows for radio update and config over USB

this allows baro offsets to be compensated for before takeoff

this prevents crashes on takeoff with barometer noise

This only triggers if the user has been using the GCS's RC override

useful for ensuring it will keep building

my mistake, sorry Emile!

Modified script rc.APM to launch modules vrinput and vroutput
Modified startup scripts to run APM without SD

Also incorporate file name changes
