Adding a script for test running.

I often forget to add --settings=collection_registry.test_settings to
the manage.py test call.
Added is_active and date joined to admin user list view.
Refactor and clean up admin filter code
Change so test-app.bash accepts up to 10 params.

Allows changing of settings and such.
Change to use mredar fork of bootstrap django admin.

Made it work with bootstrap 3.
Adding django-dbdump and script for running.
Merge branch 'master' of https://github.com/mredar/avram
use bzip2 instead of gzip for dbdump compression.

better ratio...
