Title: Move to querysets

Allows tagman to return unevaluated querysets so that we can take advantage of django's lazy evaluation mechanism.
This should improve performance and allow better widget mixins, although performance is yet to be tested.
Function ````unique_item_set```` has been left in for compatibility and convenience and will still perform the evaluation returning an item set as expected.
