c42f9ece43 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.

a9610a0761 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.

72d76558a7 ArduCopter: Ensure update_GPS does nothing when gps is disabled.

Merged CopterLEDS and Piezo functions to eliminate pin conflict on APM2.  Created new Parameter bit to turn piezo function on and off from MP. Moved GPS and Aux pin assignments to allow commonality between APM1 and 2.  Set LED_Mode parameter default to 9 in order to make CopterLEDS completely backwards compatible with old Motor LEDS and Piezo code.  Legacy users should see no difference.
