8d1a99ae15 PiOS.win32: Updated PiOS.win32 makefile for recent UAVObject changes, and also updated the experimental stabilization code to comply with recent changes to the simple code. Nobody uses SiTL anymore :( .

d2c1014e29 Re-enabled yaw stabilization after SystemSettings changed. There might be a lingering issue when the 
yaw angle crosses the zero-360 mark, beware.
You can disable yaw stabilization by setting all PID gains to zero for yaw.

77b68e5169 Flight/Guidance: Initial template for guidance module 
Flight: Create PositionDesired (the active waypoint) UAVObject and make the FlightSituationActual no update since it not used.
Flight: New velocity desired object that passes information between the look computing the desired velocity and the PID loop to get it (updated at different rates)
UAVObjects/PositionActual: Remove unused GPS fields
UAVObjects/PositionActual VelocityActual: Split the velocity into a separate object.  ALso make sure all the information telemetered around is in cm to avoid using floats.
UAVObject/GuidanceSettings: New guidance settings object for the guidance module
Flight/Posix: Add the new objects to the Posix sim
Flight/Guidance: Computes a desired velocity based on position error than runs a PID loop to control roll and pitch to achieve that velocity.  All distances are in cm, and updated the PositionActual fields to reflect this and use int32.

9b28f2d72c OP-167 OP-157 AHRS/Calibration: Added mag scale and really cleaned up calibration. 
Calibration should take less time now too (using second moments to estimate
variance in one pass).  Now need to change to multiple messages to get the
calibration in to keep the request message size minimal.  Also currently
running sensor calibrate doesn't store the gyro bias so if you want to use this
you'll have to tweak it manually.  I'll fix that step tomorrow.

Removing some Experimental and Incomplete Modules and their UAVObjects not suited for 1.0
- they will be moved into an experimental branch:

Navigation     : experimental code only
FlightSituation: experimental code only 
Guidance       : preliminary draft - possibly to be replaced by peabody124 position hold code if finished in time.

da1a762072 Added basic code for Yaw stabilisation in manual mode for Helis. 
This is functionally the same as having a heading hold gyro in hardware.
Code is copied from the simple stabilisation routine and is a bit rough at the minute, but initial testing looks good.

a6e71177e4 AHRS: Yaw stabilization now supports rate stabilization or heading hold. Also need to cleanly support rate stabilization on all the other axis. Les suggested this be in manual mode which will require changing the logic somewhat (essentially for vtol it will always be running through the Stabilization module) in an aircraft dependent manner. An alternative would be a stabilization flag indicating to do full attitude hold, attitude + yaw stabilization, or all axis gyro stabilization. This would be my preference.
