Randy Mackay 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
