29181	Move admin's flatten() function to django.utils	Daniel Hahler	nobody	"I think `flatten` from `django.contrib.admin.utils` should be moved to `django.utils`, and get modernized to not only handle nested lists and tuples.

Where should it go?  django/utils/functional.py"	New feature	closed	Utilities	dev	Normal	needsinfo			Unreviewed	0	0	0	0	0	0
