new althold PID

althold should work better now, the PID settings are preliminary. There
is definetly room for improvement.
For aquiring your own PID settings set ALT_P = 0 and tune the VEL pid
until the copter only drifts a little from its position when you
activate althold. Then set ALT_P to a value where it holds the position
stable

new althold PID
bump config version after PID default changes and add built hex file
added sumd serial receiver support by cesco/Plüschi
implement (not flight tested) brushed motors support.
set motor_pwm_rate to some value > 500 (1000, 8000, 16000 etc works on my scope).
then the motor output can be used to directly drive brushed motor fets.
PWM is rescaled to 0-base in brushed mode, so all same values of min/maxthrottle apply.
adding updated uvision project
added cli settings for pidvel
added (unsupported) GPS nav MSP numbers.
