This affects new ticket by staff as well as honoring the influence of ticket
filters on new ticket, where the status may be set to something other than
the system default. Even the system default may be influenced if it were set
to a closed state derivative.

So the concept is simple: the new status should be set using the standard
logic so that the closed_by staff member, date, events, and other
information is set as normally is when a ticket is closed.

This patch removes the selection of canned responses as well as the canned
responses navigation page from the ui when the canned responses feature is
disabled.

Allow usage of something like `%{ticket.user.organization.var}`

Faq articles should be viewed in the .thread-body div in the client portal
like they are in the staff portal.

Since the automatic lock was being acquired but not passed to the autoLock
system, the automatically acquired lock was not being release on away
navigation.

This patch addresses the issue by passing the automatically acquired lock id
to the autoLock system on ticket-view page load and change the ::Init()
method so that the lock id is not cleared with the ::Init() method is called
by the page load.

Ensure that when generating the list of acceptable file extensions, that the list is lower cased, because the extension from the filename will be lower-cased before attempting to find the extension in the list of acceptable extensions.

Do not reopen closed ticket, if the system can reliably determine that the new message is an
auto-response/reply from the end user.

- Allows the string "false" to be used in the XML payload as the documentation demonstrates, and have that be interpreted as a boolean false.
- Switching $alert/$autorespond to use isset(), and forcing those variables to be type-casted to booleans.

Take into consideration the auto-response settings when sending out new
ticket by staff notice to the end user.
