* Properly deal with Family pack downgrades by downgrading invitees to
Basic bundle.
* Refuse to downgrade Family pack if invitees don't have a recovery
email set.
* Create Invitee subscription for new invitees when they set their
recovery email.
* Move user related methods from limitmonitor.common to purist.models
module.
* Add methods to create orders and subscriptions.
* process_renewals() now also deals with invitees.
