modified MSP implementation to reflect MW2.3 changes
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.

Fix line endings to CRLF
Have servos output midrc at startup instead of 1ms pulse (full deflection)
removed rc averaging for serialrx sources - suggested by cesco
added max_angle_inclination to CLI to configure (default) 50 degree max inclination. configurable between 10 and 90 (100..900 in cli)
got rid of feature_gyro_smoothing. nobody used that, and its retarded to do anyway.

Have servos output midrc at startup
building hex file for servo center fix
Added support for fast sbus2 protocol (used by newer receivers). Untested, thanks Cesco
shows how many people use gimbal outputs.
regular gimbal rates has been broken since forever, same rate was applied to pitch and roll, instead of separate. thanx nicodh
