a147eeb1e3 INav: degrade pos error slowly on loss of GPS 
When GPS message is late by 100ms or we are glitching, degrade the GPS
vs inertial nav position error to 10% over 2 seconds instead of
immediately setting it to zero.  This avoids jumpy position estimates
when the GPS misses an update

8122a32114 InertialNav: reduce XY TC to 2.5 (was 3) 
More objective testing is required to arrive at the ideal number but 2.5
seem better than 3.0 at reducing "toiletbowling" and anecdotal evidence
does not show much downside.
