Andrew Tridgell 6839533e5d Plane: improvements to POSITION1 controller 
this improves 4 things in the POSITION1 controller based on logs from
4.2.0beta2. The changes are designed to increase the tolerance to
an incorrect value for Q_TRANS_DECEL, reducing landing overshoot

1) we fix the initialisation of the acceleration. The
   init_xy_controller() function assumes zero accel, so we need to
   call set_accel_desired_xy_cmss() just after that init to get the
   correct accel. Thanks to Leonard for this fix

2) if we decel more than expected due to too low Q_TRANS_DECEL we
   need to reduce the target speed, rather than putting the nose down

3) lower the default Q_P_JERK_XY to a value more appropriate for most
   quadplanes (Leonard suggested a value of 2)

4) fixed the pitch envelope from Q_BACKTRANS_MS to start after the
   airbrake phase is complete

ArduPilot is the most advanced, full-featured, and reliable open source autopilot software available. It has been under development since 2010 by a diverse team of professional engineers, computer scientists, and community contributors. Our autopilot software is capable of controlling almost any vehicle system imaginable, from conventional airplanes, quad planes, multi-rotors, and helicopters to rovers, boats, balance bots, and even submarines. It is continually being expanded to provide support for new emerging vehicle types.

The ArduPilot project is made up of:
