AP_Param: #include <AP_Param.h> fixups for libraries & sketches
...
* I mostly went through with grep and added an #include <AP_Param.h> below
every #include <AP_Common.h>. Not all of these example sketches might
strictly need AP_Param.

AHRS: removed AP_AHRS_Quaternion
...
this AHRS backend is causing compiler errors with the Arduino build
environment on windows. The quaternion AHRS backend is currently not
being developed/supported anyway. We can resurrect it if someone wants
to start developing it again.

Having _wind in the AP_AHRS class causes a register allocation error

DCM: drop the 'drop z' method
...
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:
http://diydrones.com/xn/detail/705844:Comment:834373
Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.
