ArduCopter - CH6 Tuning - added AHRS_YAW_KP parameter as 30.  Now you can easily set the amount that the mag is used to correct the gyro based yaw estimate in the DCM

this allows users to change the yaw gain in DCM

Rebased old branch (demo-branch) onto master in the clone to get the file
to appear and then added the text.

add connect warning to setup screen
add networkkml to georef image, and cacheing

this file will be used to help developers learn how to do git commits

fix aerosim-rc 3.91 (packet format change)
mono setup form fix (re validating disabled fields)
seperate log/live mag calibation.

dataqflashlog Update
add new test config panel

work on CodeGen
fix messagebox wrap
modify arducopter loiter options
fix setmode function
update dataflash log format- thanks randy
remove config.xml - this causes overwriting user settings

ArduCopter - Parameters.h - changed initialisation order to remove compiler warning (have not changed enum values so shouldn't require eeprom format id update)

update radio packet
fix rlogs
add left/right mavlink log graphing (left/right mouse)
modify update detector.

this adds local and remote radio noise levels

AP_MotorsMatrix - fixed stability patch issue in which it would not limit a motor's output unless an opposite motor had been defined.  This would only have affected Y6 frames.

3dr Radio support
update mavlink library

3DR R
setup layout - thanks andrew.

update message definitions
fix radio screen

AP_Motors - fixed last "shadowing" compiler warning caused by badly named parameter in auto_armed method.

AP_MotorsMatrix - fixed another compiler error regarding shadowing a variable.  Fixed by removing those  the angle and direction arrays which weren't even used

AP_MotorsHeli - fixed compiler warning re move_swash function declared with int parameters in .h file but actually using int16_t in .cpp file.  They're the same in arduino but perhaps the build checker is a little more strict that Arduino.
