Starting to get the app and db ready for multievent years and minnebar9

Luke -

Give this a look. I still can't get the tests to run and I'm not sure if that is because fixie is outdated or what. I manually in my local prod db create a new event (minnebar9) and started some manual testing. Creating sessions and things seem to work pretty good.

I think it will be good to use last year's db so people don't have to recreate accounts (as well as so we can display historic sessions by participants - at some point.)

Let me know what you think.

Cheers-
Casey
