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.

Changes in files supporting AHRS for new initialization methods.

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.

OP-132 Flight/AHRS: Changed the heuristics regarding GPS quality and INSGPS updates. Now if satellites < 7 or PDOP > 3.5 it does not perform GPS updates. Professor is working on some code to fix parts of the covariance matrix. If indoor updates high a 0 position and velocity and high variance.
