Single event page now fetches data from the backend.
Depending on the users role, different control buttons are shown.
If the user is an attendee and the event still has the 'Upcoming' status, the user can both send and remove an RSVP to the event.
If the user is a poster, they have a button to open the RSVP list modal, and a button to open the edit event modal (waiting on issue 93 to be completed).
