ArduCopter: changed all "int" to "int16_t" and a few "long"s to "int32_t".
...
Also moved "simple_counter" variable from global scope to the "update_simple_mode" function which is the only place that it's actually used.

ArduCopter: replaced abs with labs as required in a few places.
...
Also fixed a small bug in the get_stabilize_pitch function in which it was using the roll (instead of pitch) to decide whether it should let the i term build-up or not.

Airspeed patch:
...
pre-calculated airspeed resistance pitches copter automatically to gain a certain speed allowing the speed controller to work off of a better set point - similar to Alt hold.
added param tilt_comp with a default of 54 which equals 19.5° of pitch to go 6m/s

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.
