28 human readable urls

This converts location IDs in the URLs into the name of the organization + location name (if they are different), or just the location name (if they are the same). So, instead of this: http://www.smc-connect.org/organizations/521d32c51974fcdb2b0002aa, we can have this: http://www.smc-connect.org/organizations/fair-oaks-community-center
