Jaidyn Ann 6c43311982 Program-wide avatar cache
Add a program-wide avatar cache― whenever a contact or user's avatar has
changed, it gets cached in ~/config/settings/Caya/Cache/$account/People
(for contacts) or $account/Users (for everyone else).

ImageCache is now used, only for caching the kPersonIcon resource image―
it might be useful later for other commonly used images (status
indicators, etc).
