cron: Clean Expired Passwd Resets

issue: Multiple File Display

This adds functionality to clean expired password reset tokens on cron runs.

sessions: Clear On Password Set/Reset

This addresses an issue where FileUploadFields on the ticket header is not
displaying all attachments in the field.

This adds a Signal to clean Agent and User sessions upon setting/resetting
their password. If an Agent/User resets their own password and has multiple
sessions open it will log them out of every session except the one they’re
on.

queues: Column Conditions Overwrite

Relative Time Fixes:

queues: Row Conditions

issue: mPDF Arabic Fonts

This addresses an issue where row conditions are working in the preview but
not in the actual ticket queue. This updates the `getQueue()` function to
lookup the CustomQueue by `queue_id` if there is no CustomQueue object found
in the QueueColumn.

This addresses issue 4449 where using an Arabic language pack and trying to
print a ticket returns a PDF with either squares for text or no text at all.

This addresses an issue where searching for a Task by title returns all
Tasks in the search. This is due to the visibility filtering methods used to
filter tickets by staff's visibility.

This commit removes the logic that was used for time within 2 days which would give a result of either today or tomorrow when something could actually be in 2 days instead.

It also rounds relative time that is within 29 days so that the result will be more accurate.
Ex: 1.99 will round to 2 instead of showing 1

This addresses an issue reported on the forums where the ticket filter Rule
option of “Does Not Match Regex” isn’t working properly; instead it works in
reverse.

This addresses an issue where FAQ & Canned Response attachments are dropping
when another agent edits the FAQ or Canned Response.

This addresses an issue where uploading a file you’ve uploaded before but
renamed is not saving the new name in the Attachment table.
