AP_Baro - removed unnecessary 2 element average filtering of pressure (there is a 4 or 5 element average filter in arducopter code itself, two places is messy)
...
- also removed unused _offset_press variable

AP_Baro - added average filter for temperature to replace broken filter

- added average filter (for last two values) for raw pressure
- changed some "long" to int32_t and "unsigned long" to uint32_t

DCM: adjust yaw kp constant down to 0.4
...
this makes the time constant for compass errors closely match the
timing of the older releases - about 10 seconds for a 1 radian change
in heading

Compass: fixed the order of rotations in the compass driver

this should fix the massive heading issues that people have been
reporting. Please test!

AP_Declination: Added method set_initial_location
...
This will set the declination based on lat/lon if the user has
not yet saved one to the EEPROM, OR if they have specified via the
config parameter that they want it to overwrite the declination every
3D fix.
