Override the default admin queryset for some models
Because some attributes are optional or otherwise not auto-magically picked up by Django, we can help the performance of loading these pages a lot by forcing a select_related() on the queryset used by the admin. For something like signoff_specifications, this drops the query count from ~107 to 9 queries. Signed-off-by: Dan McGee <dan@archlinux.org>
