Patch from Melchior Franz:

Browse source 
It's cumbersome to use the MagicCarpet as 3D cursor, because everytime
you shoot over the target you have first to turn by 180 degrees and to
fly back.

This patch lets the magic carpet fly backwards if brake[0] is active,
which is by default associated with the joystick's fire button.
