  xss: Prevent Agent Directory XSS

This addresses an issue where you can exploit XSS in the help-topic AJAX
request. This adds a check for a refferal URL and if none it will return
a 403 Forbidden Response.

This addresses an issue where the CSRF Token is displayed in the URL
when you preform a search in the Users Tab. This removes the token from the
request which removes it from the URL.

This addresses a vulnerability where an Agent can perform XSS via the
Agent Directory’s REQUEST query string. This sanitizes the request params
so the code will be escaped and not executed in the browser.

This addresses an issue where the `randNumber()` function would crash on
32-Bit systems if the ticket format was set to a really high amount of
digits (eg. ###################). This is because the `max()` value that
was being passed to `mt_rand()` exceeded the `mt_getrandmax()` limit which
caused an error. This updates the function to generate a random number for
each digit to avoid the `mt_getrandmax()` limit.

This addresses an issue where someone can “takeover” an account with only
a User’s email and a User’s previous ticket number. Once they get access
to a User’s ticket they can go to the Ticket Owner’s profile and change
the email to whatever they’d like. This adds a check on the profile to see
if the User is a Guest User. If they are a Guest then it kicks them back
to the ticket view. If they are the actual User it will let them view the
profile.

cron: Delete Expired Sessions

This addresses an issue where someone can bypass the file restrictions on
the file upload field in the Client Portal. This adds the allowed
extensions and file types to the field options so that User’s cannot
upload anything other than the allowed file types.

This addresses issue 4015 where osTicket’s cookies aren’t HttpOnly by
default. The HttpOnly flag helps prevent client scripts accessing the
cookie. This updates the method that sets the cookie params to include
the HttpOnly flag.

This commit addresses an SQL injection vulnerability in ORM lookup
function.

* ORM implementation failed to properly quote fields, used in SQL
statements, that might originate from unsanitized user input.

* AttachmentFile lookup allowed for key based SQL injection by blindly
delegating non-string lookup to ORM.

Extend this to exclude image files that are injectable from opening in browser windows.

This addresses an issue where updating a Task does not change the
`updated` column in the database. This adds a line to change the `update`
column when updating a Task.

This addresses issue 3782 where clicking Print on a Task gives you a blank
popup that hangs. This is because the Print button was being treated as a
Task action when it is actually not one. This adds a ternary operator to
give the proper Task Actions the `task-action` class and gives the Print
button no class.

This addresses issue 3815 where searching by User's phone number doesn't
work in v1.10. This adds phone number search capabilities for the User
Directory and User Search popup in v1.10.

This addresses an issue where expired sessions would not be removed from
the database. This caused the session table to fill up and create
unnecessary issues. This adds a cleanup method to remove all expired
sessions from the database.
