Here's a patch against magic-removal that adds bulk delete to the Manager for a model class. Is this approach going to get obsoleted by the descriptor work?

(In [2029]) magic-removal: Fixed #1219 - Added bulk delete for objects.

(In [2048]) magic-removal: Refs #1219 -- added documentation for bulk delete feature.

I reopen this ticket because of the different behaviour of bulk delete and object delete with regard to related objects and relation tables for ManyToMany. ​See this discussion in django-users.
