[rotorcraft] set guidance_v_zd_sp to zero in altitude hold for visualization
[math] add FLOAT_QUAT_OF_ORIENTATION_VECT
[rotorcraft][guidance][stabilization] quat setpoint fixes

Don't pretend that the commands from guidance_h are actually real euler angles.
Compose a roll/pitch quaternion from simultaneous rotation of roll/pitch,
then rotate around resulting body z-axis to align the heading.

This should "fix" the setpoint passed to the attitude stabilization if in HOVER or NAV
at large angles.
Only tested quickly in simulation...
[rotorcraft] guidance_h: normalize psi sp from nav_heading
[rotorcraft][stabilization] calculate correct yaw from guidance psi setpoint

Instead of using the psi setpoint angle to rotate around the body z-axis,
calculate the real angle needed to align the projection of the body x-axis onto the horizontal plane
with the psi setpoint.
Only makes a few degrees of difference at high roll/pitch angles, but should be correc now.
still needs to be optimized...
[Ardrone] Full Auto2 Flight in RAW Mode

[superbitrf] Initial commit for superbitrf 2.4GHz radio control
[superbitrf] Now got a full RC working, still needs testing.

Binding could be improved but already works about 30% of the times you try.
[superbitrf] Less RC Lost and fixed message

Implemented to make it only resyncing when it lost 2 packets of data. Also fixed the message to show the correct status of the CYRF6936.
[superbitrf] Downlink is now functional

Still needs some extensive testing to make it more relaible.
DSMX implementation
Some small fixes
