try to ensure we end up with a timeout display on the website

the Camera and Mount code make it impossible because of the incredibly
silly arduino cpp handling.

if a UBlox is configured for NMEA only, with no UBX messages at all
then it would never trigger the GPS_AUTO detection. This adds a UBX
config message to the init strings that enables the NAV_SOL message

this allows the caller to wait for the tx buffer to drain

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.

So disable CLI when MOUNT is active. Sorry I did not detect it before, but the APM_Camera branch worked in a different way.

Add this line to APM_Config.h to enable Robert's yaw
#define ALTERNATIVE_YAW_MODE ENABLED

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)

hopefully it will stay building

I have no idea if it will actually work, but at least it builds
