Budgets App

Add a new application to allow budgetary data to be added to $things in Pombola.
I don't think this is going to work as a lot (all?) of the places on the live site have "-2013" appended to their slug, e.g. http://info.mzalendo.com/place/ainabkoi-2013/ or http://info.mzalendo.com/place/rabai-2013/. I guess you could just try and match on name or something then give an error for any that don't match. Whichever way you choose to do it it's probably best not to use `get_or_create` as we don't want to end up with duplicate places.
