Remove empty directories
Remove vlad remains in the Rakefile
Remove capistrano deploy file we don't use
Use file_store as cache for production

Getting rid of that, also allows us to let the following
things go:
* Devise
* Warden
* Cancan
* Various Controllers
* The User Model
* The User Table
* User management
* All the layouts for logged in users
* The address view
Normalize the tags and use a json importer for addresses in seeds
