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.

2dc40d11a1 Flight/Stabilization: Use the system clock to determine time from previous 
update since now drive by events.  This means StabilizationSettings object
changing so write down your settings.

4461aba6d6 Flight/Stabilization: Move to object event system. Latency from ahrs_comm 
update to actuator update now ~0.7 ms.

aa42256ad1 Flight/Stabilization: Convert all PID loops to units of seconds instead of ms. 
THIS MEANS YOU MUST RETUNE YOUR PID LOOP IF YOU'RE FLYING WITH IT

Alternatively divide Kd by 1000 and multiply Ki by 1000

11f2b1a8dc Flight/Stabilization: Dont cap error at maximum stabilization value - that is to scale control throws. Create another variable if we want this.

3b015b41c5 Flight: Got a much nicer arming/disarming system going. Made it a separate flag in the end to allow testing the stabilization code with motors not running. Also changes maxRoll/maxPitch/maxYaw to uint8 to keep object size smaller - no reason for float precision for this.

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.

c376711405 Flight/Stabilization: Make the derivative account for the sampling time (dAngle/dt) for the PID loop since integral does and also make the integral bounds uavobject settings. It was originally bounded by constant/Ki but I'm not sure why as you change the gain of the error integral you also want to decrease the maximum error it can cause.

65dc5e9b04 Yaw stabilisation for the simple algorithm was calculating the error and not taking into account that 350º error is the same as -10º error. 
The resultant error could range from -360º -> +360º
Since this is only used for Helicopters / multi rotors, and the aircraft can rotate in any direction, I added the modulo logic so that it is now from -180º -> +180º this should now take quickest path to correct the error.

2361af19fb First attempt at ccpm mixing for single rotor helicopter. 
This has throttle and pitch curves implemented and can be configured for many swashplate configurations.

This has flown a 450 clone (with training wheels) and the ccpm worked well.

Still need to neaten up some stuff and work out how to implement yaw stabilisation in manual mode.

2621d07574 Added UAVObjects: FlightSituationActual NavigationSettings NavigationDesired 
- Added FlighSituation Module (development module for sensor fusion, mostly stub, possibly renamed later)
- Added Navigation Module (development module for navigating towards a point in space - DEVELOPMENT CODE, NOT STABLE YET (I am testing around with this)) 
- Changed Stabilization Module (uses local reference frame now. Stable except for code cleanup/review. Tested in simulator and outperforms old code.)

c74eb2f0e9 OP-26 Flight/Stabilization First release of stabilization module. Tested using FlightGear, default tuning is for the HITL simulation. Works fairly well but a number of improvements can be made to aid tuning. The ManualControl settings must be first set as you would normally do for HITL simulation, flight mode is changed using the mode channel.
