Copter: remove cli eprom dump
Copter: increase default battery capacity to 3500mAh
Copter: add params file for Iris
Plane: added FS_ACTION of 2 for glide

this allows people without specified settings in their receiver for
failsafe to choose FBWA zero throttle glide on throttle failsafe. That
can be a better choice when flying at a R/C club field

SITL: added SIM_SERVO_RATE parameter

this allows a slew rate for servos to be specified in degrees/second
Rover: fixed typo
AP_SteerController: change the scaling of the D term

this should cope better with low speed
AP_Math: fixed float rounding in location_offset()

this prevents rounding of positions in the rover code
autotest: added takeoff to CMAC-circuit.txt
autotest: fixed heading in CMAC location

point along the runway
SITL: reduce default GPS delay to 0.4

closer to real uBlox delay
AP_GPS: fixed an initialisation problem with GPS drivers

before the first full packet arrives we could report uninitialised
values for groundspeed and heading
autotest: run mavproxy.py from $PATH
Plane: use the projected position for geofencing and waypoints
