in_bulk should use duck typing so that listy-objects can be used, like ValuesListQuerySet

Currently, using a ValuesListQuerySet as a parameter to in_bulk returns an exception, even with flat=True:
AssertionError: in_bulk() must be provided with a list of IDs.
This is due to this line in query.py (line 416 in 1.3) :
assert isinstance(id_list, (tuple, list, set, frozenset)), \ "in_bulk() must be provided with a list of IDs.
Which requires a certain type, rather than just something that can be iterated upon. I think it'd be more valuable if it was just something iterable, like ValuesListQuerySet is.
