automatic generation of LANGUAGES list in settings.py

[Akihiro Motoki]

At now, LANGUAGES list in openstack_dashboard/settings.py is updated manually. It is better to generate the language list automatically based on the existence of PO files.

In horizon, there are four types of PO files ([horizon/locale, openstack_dashboard] * [django, djangojs]). It looks better to check whether all four types of PO files exist in the repo and list such languages.
