Inertial Control
...
I added inertial navigation based on the simulator data. This is an option only available if you compile with Arduino and set
#define INERTIAL_NAV ENABLED
in the APM_Config.h file.
This has been tested for one real flight and did not crash my quad, but consider it very alpha. The quad may be unpredictable at first until the error correction fixes poorly calibrated accels. Be Careful.
Most of the real work is in the inertia file, but the error correction, new variable defines and calibration calls are sprinkled throughout.
The Log should record RAW messages with special debugging values.

Loiter_P (speed from distance to target) = 0.2 (was 0.35)
Loiter_Rate_P (lean angle from desired acceleration) = 2.4 (was 2.5)
Loiter_Rate_I = unchanged at 0.08
Loiter_Rate_D = 0.40 (was 0.45)

Stabilization patches
...
removed Angle error limit for stabilization
constricted Iterm to +- 5° error and limited the implementation to when the quad is +- 5° from center
doubled the output limit for Rate controller.
increased default Rate_P gain to .18 with matching Rate_D of .004
Tested in the SIM and in backyard. dramatically increases performance and quad no longer overshoots and flips when pushed hard.
