Confirmation fixes

This includes the confirm email fix, a placeholder page where newly confirmed users are sent to, and the two plans for the front page that we'll decide on one for sure today.
This isn't part of this particular PR, but I'm wondering if we even need the /users/login route specified with Devise in place. Maybe Adam will know. Also, the generic /users/:action routes for both get and post seem unnecessary. Having something like that for "get" only on the home controller where all the routes are "get" only views could make sense. I'd be hesitant to put something that generic though on the users controller and would be specific or use something more RESTful if possible.
