Increase GPS position timeout to real-life timeouts. More work needed.

This increases the timeouts to a more reasonable scale. We need to invest some more thought (in a separate PR) into this, because dropping out of auto only makes sense if we've still got a RC control.

Need to start logging the commander state more completely.
Agree too. As I noticed, for good GPS reception EPH/EPV both are small, but for bad EPV grows much faster than EPH.
