Import spanish locale from FCO.

I had to manually fix a few situations where the key names had
changed between us generating the CSV they used and finally getting
it back. It's possible we could make that better by ensuring that
the importer doesn't remove any keys.
Import the french translations from FCO.
Adding Arabic from FCO
Fix YAML that was causing the app to barf.

Given this was actually generated using the YAML library, is that a bug?
Add missing translation key

Fix another FR translation

This clearly isn't sustainable - we should probably mock these out or similar.
