* Commit a variety of fixes to bugs discovered while trying to fix the NaN singularity.

* WebStatsModule doesn't crash on restart.   GodsModule doesn't crash when there is no Dialog Module.  LLUDPServer doesn't crash when the Operation was Aborted.  
* ODEPlugin does 'Almost NaN' sanity checks.
* ODEPlugin sacrifices NaN avatars to the NaN black hole to appease it and keep it from sucking the rest of the world in.
