Fixes three issues:

#65: When submitter clicks 'Accept' to accept a resolution, nothing happens.

#74: issues when updating ticket via views.staff.update_ticket (which is also used by the public views) relating to invalid template 
context and inconsistent variable naming.

#82: Add an option for users to control the number of tickets per page.

Thank you to J. Beigel and Christian Klein for these suggestions.
