Refactor to Mixin

[mbleigh]

Make the TwitterAuth functionality a mixin instead of a superclass, so that TwitterAuth can be more configurable and added in a less strict manner.

Example:

class User < ActiveRecord::Base
  twitter_authenticated :via => :oauth
end

This is perfect for those of us wanting to add twitter login as an optional way to authenticate, in addition to traditional login with username and password

Ok, this is something I'd like to tackle in the near future. This is my proposed laundry list, tell me if I'm missing anything:

• Allow TwitterAuth to be added to a model via a twitter_authenticated mixin
• Allow enough configuration to keep it from conflicting with other authentication solutions. (I might namespace all of the functionality into a proxied twitter object that does more than the current dispatcher).
• Remove the validations from being required (this way apps that don't solely use TwitterAuth can have blank fields for some of those fields).
• Support legacy versions of TwitterAuth by making the GenericUser automatically call twitter_authenticated
• Tweak the generator to take advantage of the new refactor.

Obviously this isn't a small task and I'll be starting work on it in a mixin branch sometime soon.

Any progress on this? I am also having trouble getting my application to logout. I understand that I can use the /logout path from the sessions controller, but it does not actually sign out of twitter after destroying the session. As a result, I just end up looping back through the automatic login. Any suggestions?
