Update to Rails 3.2.13

* update to Rails 3.2.13
* had to update to Devise 2.2
* Geospatial gems were not working properly with Rails 3.2
* Switched to Geocoder gem for Venue geocoding
* removed custom built geocode.rb

I definitely had to modify the Venue model and table here. Too many changes just to get to Rails 3.2? I think they were all necessary.
