* Updates the sim stats module. Cleans out some of the rot.

* Adds a prototype web stats module which is disabled by default.  It's functional with one report right now, however, the database structure may change, so I don't recommend enabling this to keep actual stats right now.  I'll let you know when it's safe.
* Adds Prototype for ajaxy web content
* removed a warning or two.
