Docs suggestion vis-a-vis staticmethods

[roysmith]

It took me a bit of head-scratching to figure out why

@cache.memoize(timeout=30)
@staticmethod
def from_nomination(nomination):

doesn't work, i.e. you need to do:

@staticmethod
@cache.memoize(timeout=30)
def from_nomination(nomination):

following the same logic as described under Caching View Functions. You might want to mention this in the docs.

PS, while we're there, in the warning box, "If you reverse both decorator" should be "If you reverse both decorators" (plural).
