[Events 2.0] Have Add-Ons visible when viewing tickets.

Dashboard for Ticket Orders in the Events Section should include add-on information. Right now, that's just not visible at all unless you do a full export.

From email reply:

I wanted to see the add-on information alongside the ticket information in the orders tab. So if someone gets an admission ticket then purchases an add-on item, I don't have to toggle through multiple tabs to see what they ordered.
