Ticket Listing Content

[samozzy]

Allow the option to have content before and/or after the ticket listing.

This should be by means of an include {% include ticket-listing.html %} which inserts a div with the appropriate id (mini-list or whats-on), so it can be included in between content sections, should that be desired.

The ticket JS should then work out if that div already exists: populate it if so, or add a new div at the end of the content section if not.
