Add a location model that can be used by MediaEntry, User, Collection and MediaComment so that location data from other servers in the pump.io API can retain this data and see it. This has been outlined ​here.

After a system python upgrade, Mediagoblin won't be able to start any more because the local virtualenv python will still look for the old python modules (if I understood correctly). Mediagoblin will output errors like this and refuse to start:

To update virtualenv python you can issue:

virtualenv --system-site-packages <path/to/env>

as mediagoblin user, where <path/to/env> is the path to your mediagoblin instance.

Very similar to #973 (but not yet confirmed that it has been causing issues), it seems that there isn't proper transaction/session closing behavior in the garbage collection tool implemented in the garbage collection celerybeat task.

We should make sure this is working correctly and then re-enable by 0.8.0. It's a very valuable feature and we don't want it to fall by the wayside.
