Routes configuration

The more specific and detailed routes should be defined first so they
may take precedent over the more generic routes. For more information
refer to the routes manual at http://routes.groovie.org/docs/

IMPORTANT: if you change any routing here, make sure to take a look at lib/base.py
and _route_name variable which uses some of stored naming here to do redirects.
