The subs_* functions in subs.php have made a lot of assumptions about users versus profiles. I've refactored the functions to be methods of the Subscription class instead, and to use Profile objects throughout. Some of the checks for blocks or existing subscriptions depended on users or profiles, so I've moved those methods around a bit. I've left stubs for the subs_* functions until we get time to replace them.
