Move translations to babel locations.

If we structure things like this, we can get things
actually, you know, installed.

Locales ast and oc aren't supported by babel. We'll re-import them
from Launchpad once we get babel updated.

If you want translations installed, run:

  python setup.py compile_catalog

Before you run either setup.py sdist or setup.py install

More work is needed to actually properly use the installed translations, but
we're closer.
