Fix issue #3268

This fixes sorting and total ticket count.

orm: Delegate ResultSet calls to QuerySet Iterator

orm: Fix warning for read-only role permission, cleanup Dept::getMembers() usage

oops: Fix join for sorting tickets by priority column

Make `cron` signals conform to documentation.

export: Fix crash exporting users

The [signal documentation]
(https://github.com/osTicket/osTicket/blob/develop/setup/doc/signals.md)
for the `cron` signal states that the context is `null`. But it was
missing until now (and the `$data` parameter was wrongly forwarded as
`$object`)

In ::isMember(), there is now no reason that a call to ::getMembers() would
fail, so it can be assumed that a QuerySet instance is returned.

This fixes an issue where the `$ht` variable is not properly initialized by
the ORM. It is assumed to be a valid array in the constructor, and its items
are run through the ::set() method. Therefore, if an empty array is
received, the `$ht` variable will remain null, since nothing is ever set.

This also fixes a misspelled variable in the claim dialog if a ticket is
currently assigned to a team only.

Fixes #3194

This fixes files disappearing when uploading multiple files. Only one file
at a time is uploaded to the server.

This is important to show custom statuses with properties.

This is required for system requests such as email piping. Since a user is
not logged in for the request, the system locale will not be set and text
might get corrupted based on the PHP configuration.

Change recipients active/total count on update

Allows for ability to access results without the need to call getIterator on
the QuerySet. For example - $this->members->findFirst(array(...));

This commit addresses regression issue brought about by commits 8ab4432f and
eb0ba316 -- where ResultSet processing changed based on caching mode.

With the advent of the MANIFEST file, files which are rewritten when
deployed, such as those which have the GIT hash in the query string to force
browser reloading, were no longer deployed unless the content of those files
changed.

This patch adds a flag to the MANIFEST file to indicate that the file was
rewritten when it was deployed. This allows the file to be deployed and
rewritten again when the deployment is run, but also adds an indication
to the console output to distinguish deploying changes as opposed to
deploying rewrites.
