Fixes for my-tickets view and public ticket view

[timthelion]

We didn't set the secret key in the urls in the my_tickets view so it wasn't possible to actually comment on tickets visited from this view.

You have to merge the other two PRs I submitted before this one...

Translation fixes in my_tickets.html:

                <th>Title</th>
                <th>Queue</th>
                <th>Status</th>
                <th>Created</th>
                <th>Due Date</th>
                <th>Submitter</th>

->

                <th>{% trans "Title" %}</th>
                <th>{% trans "Queue" %}</th>
                <th>{% trans "Status" %}</th>
                <th>{% trans "Created" %}</th>
                <th>{% trans "Due Date" %}</th>
                <th>{% trans "Submitter" %}</th>
