Friendly suggestions

Ok, so I saw @datachomp open this project up.  I took a look, and I thought I'd throw in a few suggestions.  

I did this while watching tv, so don't trust everything... my attention was spread out.  

So here's the payback to AR's models, with the has_manies and the belongs_tos... our view just became a little messier.

I'd say that ```@agenda.venue.venue``` is better than writing a flattening query in the controller... but it is creeping into evil land.  Someday later we could talk about view models in Ruby, which can be **very** nice for this sort of stuff.
