Tentative pull request

I've implemented a ton of stuff, and only tested some (everything in wamp should have good tests). Basically I've:

* added ParseType- gets the message type from a byte array (uses regex currently)
* changed type of EligibleList and ExcludeList to []string
* started a Turnpike server (completely untested =D)
  * sends a Welcome message, listens for requests and handles pubsub
  * panics on things not implemented (Call, Prefix)

This definitely isn't ready for production, but at least it should give you an idea of where I was thinking it should go. Go ahead and change everything if you like. I'll start working on getting a stupid simple chat room working.
