This is required with the connection to Dept::getEmail()->send(...)

The bug was partly due to switch to ORM.

* Fix crash saving a page (regression)
* Fix red banner deleting a department
* Fix crash deleting a knowledgebase article

If a relationship has more than one field in the constraint, then the
InstrumentedList query generated would not be correct. This happens often
in osTicket for the join foreign key fields `object_type` and `object_id`.

This patch addresses the issue by sending all the fields in the foreign key
to the InstrumentedList constructor.

Add support for passing a criteria to AssignmentField to limit  the choices
Limit assignees based on department settings
Cache choices

Unassign tickets on transfer when the target department has assignment
restriction and the assigned staff is not a member.

Disable claim (quick self-assignment) when above restriction is in effect.

  * Fix fatal errors adding a new FAQ (fixes #1648)
  * Fix removal of attachments when deleting a thread (fixes #1650)
  * Fix crash discovering department members for alerts (fixes #1652)

This patch adds a ::getAlertEmail() method to the Department class, which
allows administrators to use the department email address (normally for
replies) as the alert email address. If not specified, the system alert
email address is retrieved instead, automatically.

Support duplicate names in different hierarchy
Save path on add/update
Show full department name on transfer

This significantly reduces the time necessary to render the ticket queue
page with the ORM.

Departments without email will use the system default email as the default
outgoing email.

Add department setting to limit ticket assignment within department to
department members only. This is necessary for departments with strict
policy on who can access tickets.

The setting doesn't limit team assignment or auto-assignment via help topics
and ticket filters.

Clear ticket routing settings on topic, email or filter tables on department
deletion.
