Approval for #1361

@mrwweb proposed three changes in #1361:

• Displaying the number of checked-in attendees in the Attendance UIUI UI is an acronym for User Interface – the layout of the page the user interacts with. Think ‘how are they doing that’ and less about what they are doing. tool.
• Renaming the Published post status for tickets to Registered
• Assigning tickets to a new Attended status when attendees check-in

What does everyone think about those?
