Clean up security code a bit
Make it possible in the back-end for an owner of a queue position to un-queue
Make the "Remove" button show up for queue positions you own
Disable custom error page (useful for development)
Hide form instead of table cell when Remove button is absent
Only require admin access to always see queue position remove button
Use ng-if instead of ng-show for performance reasons
