Hatbox integration (Patreon)

Turns out that there is a way to integrate Patreon payments into Drupal subscription processing! It will probably take two months or so to work this out and implement because it is very complex and other things (like hardware upgrades) are more pressing.

This effects Patreon right now since there is now no pressing need to migrate Hatbox content to Patreon format. We will continue adding new Hatbox content to Patreon as well as Hatbox.
