 Ming 0.4 removes the `__len__` method which does a count() query.  This is so that list(query) and query.all() don't cause that to run any more.
 
 We'll need to find & change all our `len(query)` and `query|length` (in templates) to `query.count()`.

-If we're not comfortable with finding these manually via test runs, searching, and exercising all parts of Allura, we could potentially add support in Ming to inspect the frame within `__len__` and if it's not a call from `list()` then raise a DeprecationWarning.  (We can't simply raise DeprecationWarning all the time since list(query) automatically calls `__len__` under the covers)
