* 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.
