Arne Brutschy f3e52a2f12 Adds pre-defined values for public tickets
This commit adds three new settings that allow the operator to
pre-define the `queue`, `priority` and `due_date` fields for public
tickets. If one of these settings are present the corresponding input
field is hidden from the form.

The settings are the following:

    HELPDESK_PUBLIC_TICKET_QUEUE = 'website'
    HELPDESK_PUBLIC_TICKET_PRIORITY = 2
    HELPDESK_PUBLIC_TICKET_DUE_DATE = ''

If the due date is set to the empty string, no due date is saved in the
ticket (analogously to the form). The other settings should be
self-explanatory.
