velocity to help stabilize attitude. In principle the mag should be fine but
in practice I need this.

indoor from the name since it's used for both indoor and outdoor mode now.
Increased default value to 0.4 to better reflect the GPS accuracy.

how various sensors are used in the INS update. Also added slow filter to
track offset between GPS and baro in outdoor mode.

Changes in ahrs.c for new initialization and to fix issues with outdoor algorithm. The changes in ahrs.c are pretty messy, but committed mostly to get the code to Peabody for more extensive restructuring of ahrs.c.

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

moved around where the axis are swapped and made the negative sign come from
calibration.

uavobjectgenerator to support multiple fields (thanks Les!). Also
changed default scale on mag to +/-6g

home location. If you use INSGPS_INDOORS make sure your HomeLocation.Be fields
are correct for your GPS coordinates

fly (EKF rate up to a limit). Also, now the algorithm selects if you are
indoor or outdoor as well as if you use a mag indoor (if you do set the z
variance higher than it calibrates to).

approach again because ran out of numerical precision for single pass. Also
made ground force the gyro signs to be correct.

Flight: Create PositionDesired (the active waypoint) UAVObject and make the FlightSituationActual no update since it not used.
Flight: New velocity desired object that passes information between the look computing the desired velocity and the PID loop to get it (updated at different rates)
UAVObjects/PositionActual: Remove unused GPS fields
UAVObjects/PositionActual VelocityActual: Split the velocity into a separate object. ALso make sure all the information telemetered around is in cm to avoid using floats.
UAVObject/GuidanceSettings: New guidance settings object for the guidance module
Flight/Posix: Add the new objects to the Posix sim
Flight/Guidance: Computes a desired velocity based on position error than runs a PID loop to control roll and pitch to achieve that velocity. All distances are in cm, and updated the PositionActual fields to reflect this and use int32.

Calibration should take less time now too (using second moments to estimate
variance in one pass). Now need to change to multiple messages to get the
calibration in to keep the request message size minimal. Also currently
running sensor calibrate doesn't store the gyro bias so if you want to use this
you'll have to tweak it manually. I'll fix that step tomorrow.
