Parameterized Conversation Structure

[ddfridley]

Currently the majority of the operation of a candidate-conversation is in the undebate module - everything from the splash screen through the thank you and feedback panel is handled in it, in code. If we wanted to create another structure - such as the town hall, we would have to create another module like undebate, but different.

We would be able to create new discussion structures faster if we componentized undebate so that an undebate were a series of modules, and what series to use is determined by the parameters set in the database.
