This commit addresses the root cause of an issue commit 96892beb (now
        reverted) attempted to solve - by providing consistency between
getFiles and getAttachments

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 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 alphabetizes all Role and Staff Permissions.

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 it appeared as though tasks could not be assigned to teams if an agent in the team was not a part of the task's department. The assigment was actually taking place, however, it was not showing up in the Assignee column. Now the form will correctly display the column

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

This addresses an issue where FileUploadFields are displaying the old names
of existing files with new names.

This addresses an issue where the client portal shows Featured FAQs on the
sidebar even thought the Knowledgebase is Disabled.

This addresses an issue introduced with `9ab2317e` where the icon for the
event still shows even though we continued and didn’t return the event
description.

This reverts commit 14bcd42d.

This addresses issue 4155 where editing a ticket using a different session
causes custom file uploads to drop from the ticket.

This addresses an issue where deleting a field and all it's data will
delete the form field record in the database causing all events containing
the field to crash the ticket page.

This addresses an issue with PriorityField Template Variables introduced
with 4359 where the priority variable will appear as "Array" instead of the
actual value. This adds an `asVar()` function to `class PriorityField` to
get the appropriate data.

This addresses an issue where the client side thread entries are all grouped
within the same div. This pushes all grouped entries to one side of the page
making them illegible.

- Add space between column headers and sort arrow
- Fix sorting by 'Subject' column
- Fix redactor issues with 'Reset' button
	- Make sure text within redactor is cleared correctly
	- Make sure we don't keep attachments if Reset
- Make sure redactor is reinitialized where needed

This addresses an issue introduced with 4332 where the deploy CLI breaks
upon deploying to an existing location. This checks to see if there is a
bootstrap file in the destination first and if so it uses that one if not
uses the source.

This addresses an issue where client side column sorting does not work at
all. This is due to the if/else statement that checks for a REQUEST sort
order and if the REQUEST sort order matches an `$orderWays` array value. The
if statement returns TRUE for DESC and sets the sort order to DESC as it
equals '-' (a dash) but ASC equals '' (an empty string) so it returns FALSE
which fails-over to the else statement setting the sort order to DESC. In
addition, this adds sorting icons the the column headers to make it more
obvious they are sortable.

This addresses an issue on the forums where osTicket does not add the proper
values to any custom choices field template variable. This adds an `asVar()`
function to `class ChoiceField` so we can return the proper values for the
template variables.

This addresses an issue introduced with a3d896c8 where TextThreadEntryBodies
are not keeping their new line characters causing the email format to appear
wonky. This balances the entry and then htmlchars it to ensure no XSS.

This addresses an issue that was introduced by a previous attempt to
address the orphaned file query. The previous attempt addressed the
original issue but slowed database performance so this addresses the
performance issue.

This addresses an issue where osTicket did not ensure associated items exist
before saving to the database. This also addresses an issue where the Parent
Topic error was not displayed on page.

It may be possible to steal or manipulate customer session and cookies,
which might be used to impersonate a legitimate user, allowing the hacker to
view or alter user records, and to perform transactions as that user.
Sanitation of hazardous characters was not performed correctly on user
input.

osTicket did not properly sanitize array values in `Format::htmlchars()`.
Some values in the Admin Interface were not properly sanitized and returned
to the response.

This addresses an issue on the Forums where the Auto-Assignment Thread
Event (configurable via Help Topic) uses the Email of the User rather than
the User’s Name. This adds the correct function to retrieve the User’s
Name if the User has an Account.

This addresses an issue where disabling Ticket Locks but setting a time
for the Lock Timeout will always throw a "lock required" error. This adds
a check to see if locks are enabled AND there is a time set. If locks are
disabled it will not throw the error.

This addresses issue 4329 where you can import a User with no email
address via CSV file. Once the User is added and you try to update them
with an email address it fails due to no default email. This updates the
check for email address from `!isset()` to `empty()` which will correctly
check for empty string.

This addresses issue 4322 where deploying via CLI is missing
`bootstrap.php`. This is due to the `get_include_dir()` function that
tries to include a file from the destination which doesn’t exist yet,
causing a fatal error. This updates the function to use `$this->source`
instead of `$this->destination` to correctly find and include
`bootstrap.php`.

This addresses issue 4325 where the Language Pack Locales are mismatched.
The Locale for the first language is displayed on the second language,
etc. This updates the `$manifest` variable to be set before we display
data so the correct `MANIFEST` file is included and all language data is
displayed correctly.

This addresses an issue where the Help Text for Section Break fields does
not display custom Redactor styling correctly. Instead of displaying the
properly formatted Redactor content with it's styling it displays the
entire html for the Redactor content. This was due to the format method
used for the Section Break Field's Help Text. This updates the method from
`Format::htmlchars()` to `Format::display()` which displays the properly
formatted content. The content is also sanitized by `Format::sanitize()`
before saving to the database to avoid any chance of XSS.

This fixes an error where the ModelInstanceManager maintained a reference to
the QuerySet instance, and the QuerySet instance managed a reference to the
ModelInstanceManager instance (if it's the iterator for the query). Because
of the circular reference, if the iterator is not exhausted, then the
resource is not closed and the query remains open. This wastes memory and
prevents some other queries from running after such a situation happens.

This addresses the issue by removing the circular reference between the
QuerySet and the ModelInstanceManager.

Don't display the Close Task option if the current user can't close it...

This addresses an issue where some Vimeo videos are not being sent in
Agent’s responses. This adds `player.vimeo` to the sanitize method’s
iframe section so that the iframe tag is not stripped.
