commerce_event_ticket 7.x-1.0-alpha3

This is an alpha release, intended to be used in development and testing. It is not recommended for production use.

Significant changes since 7.x-1.0-alpha2:

• core: Added the ticket 'number' and 'quantity' fields. While each ticket is supposed to admit 1 person only, it is useful to see its position among that person's other tickets, e.g. "Ticket 1 of 2", "Ticket 2 of 2", etc. That's what these fields represent.
• cet_services: Exposed the ticket number and quantity via the 'position' key in data returned from the event-ticket/BARCODE service.
• cet_services: Added a permission so that a ticket checker can view all information from the event-ticket/BARCODE service, including order data.
• commerce_event_ticket_pdf: Fixed a minor bug where records in commerce_event_ticket_pdf were not always being deleted when related file entities were deleted.
• commerce_event_ticket_pdf: Added ticket metadata at the bottom of the page (including "Ticket 1 of 2", etc.), as an optional 'footer' element. This doesn't use the TCPDF::Footer() functionality as that appears to be unnecessary.
