Title: WMM2010 Geo model from Sergey for v4.1

I picked Sergeys commits from #241 and made a few minor cleanups..

Still needs a bit more work:

* should not depend on ahrs_int_cmpl_quat
* should not depend on rotorcraft firmware (autopilot_motors_on)
* wmm files should be pprz_geodetic_wmm2010.[ch] in sw/airborne/math
