Template tweaks from refactoring / Django1.5 migration

1. Admin templates were moved to the wrong location `distributed/templates/distributed/admin` instead of `distributed/templates/admin`; fixed so the Django admin panel keeps the KA Lite look & feel.

2. 'adminmedia' is contained in the `Chronograph` admin templates but was removed in Django 1.5.  Remove them (they're no longer needed).

Testing:

* Go to Django admin, browse Chronograph.  If you don't see exceptions and it uses the KA Lite base format, you're golden :)
