Override the default admin queryset for some models

Browse Source 
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.
