Mark class as a StateMachine {github.com/aasm/aasm}

Specifically it:

* Adds the methods in {InstanceMethods} to the class
* Blacklists the "state" field so it cannot be set via the API
* Allows access to the "state_event" pseudo field from the API
* Sets up the aasm library with the contents of &block
