1) Moved the criteria for using GPS to defines in anticipation of moving into AHRSSettings 2) Only use the mags for updates if the vector length is within 20% of nominal to avoid updating when it's nonsense 3) Reinitialize position when swapping between indoor and outdoor 4) Dont use mags for first 5 seconds after initialization, sometimes seems to cause issues 5) Dont use mags until magnetic field at your location is set and a magnetic field is loaded 6) Dont use GPS if home location hasnt been set git-svn-id: svn://svn.openpilot.org/OpenPilot/trunk@1959 ebee16cc-31ac-478f-84a7-5cbb03baadba
