Sometimes an MTA may just send back the headers of the original message
rather than the entire original message. Such an email will have a
`text/rfc822-headers` part which will be the complete headers of the
original message.

Without this patch, osTicket will create a new ticket for the bounce message
rather than attaching the new internal note to the existing ticket.

Consider closed date to determine ticket's last activity date. The net effect is closed tickets queue will be sorted by closed date.

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

The setting is useful in making sure the staff members with access to the
department can get alerts and available as possible assignees.

Accept desired $format as part of class instantiation. System default is
used when none or an invalid format is provided

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.

This patch uses a 'StringView' to create a string which is a window of
another string. The __toString() method is employed to fetch a lazy copy of
the window which can be usually immediately discarded. This is optimal for
one-time-use string copies like what is used in the mail parsing.

Previously, the new internal note alert was only sent to the assigned staff
member, if any were assigned.

Previously, there was a bug in the ORM where magic properties would need to
be declared in the model class.

Provide quick prints options that bypasses the print dialog modal

Disable email alert sent to admin when a warning is logged due to ticket
rejection e.g when banned email or max open limit is reached.

Conflicts:
	include/class.orm.php

The ThreadEntryWidget has a potential cross site scripting (XSS)
vulnerability if data was posted directly to the page hosting the widget

Vulnerable URLs:
view.php, open.php, scp/open.php, scp/tickets.php

The content received in the HTTP POST is now correctly escaped when it is
echoed back to the user agent.

Images placed in the "Issue Details" in a new ticket by staff are not
correctly translated to the standard used in the storage model in the
%ticket_thread table nor for the standard used by the email system.

This patch changes the logic used to create the email template to fetch the
sanitized and converted message body from the ThreadEntry instance created
rather than reusing the raw message originally sent in the request.
