Users can now delete tickets

Added a button widget on the ticket detail page that will call a view that will delete a ticket. It also has a link to go back to the project page, and it contains a stub link for the edit ticket page. All someone would have to do is create a view that allows a user to edit a ticket. In fact, they could use the same view as Juans add ticket view most likely with some minor modifications. If anyone is actually reading these here is a joke:

A mushroom walks into a bar,
Bartender says to the mushroom "we don't serve your kind here"
The mushroom replys "But I am a fungi!"
