* Print event.registration receipts.
* Refunding a pos.order will cancel the event registrations.
* Support pricelists.
* Refactored code for better overrideability.

EventEventTicket inherits from EventTypeTicket, so we don't need to duplicate the field declaration, if it is the same in both module. This ease overriding, as we need to override only one model, if we expect the same behavior in both.
