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 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.

Display Loading Overlay when posting a response or a note to a ticket.

* HTTP Option: TRUSTED_PROXIES (default: <none>
To support running osTicket installation on a web servers that sit behind a
load balancer, HTTP cache, or other intermediary (reverse) proxy; it's
necessary to define trusted proxies to protect against forged http headers.

* HTTP Option: LOCAL_NETWORKS (default: 127.0.0.0/24)
When running osTicket as part of a cluster it might become necessary to
white list local/virtual networks that can bypass some authentication
checks.

* Validate CLIENT_IP to make sure it's a valid IP address.

Encode html chars on helpdesk title

Use class instead of id on form element that triggers overlay on submit.

Account for agents' name format setting when sorting agents.

Fixes #3194

This is important to show custom statuses with properties.

Add a preview tool tip to show list item properties on mouse-over.

Corrected "over-W-ridden" and removed the unnecessary "w" from the word "overridden"

Fix a bug where it was impossible to disable ALL collaborators
Change recipients active/total count on update

In addition to 71a6b2a0 splitted "this department" here.

This feature adds a setting to the control panel to require signing in to
view attachments. This is in addition to the security already provided in
the download URLs. Currently, download URLs are signed for a specific help
desk, and automatically expire after about 24 hours. The exact timing is the
following midnight allowing for at least 12 hours cache time.

Administrators can impose this extra security feature to refuse serving
attachment files if the user is not currently signed in. This could prevent
third-party users from viewing an attachment if they were able to get access
to the download URL before it expired.

* Separate primary from extended access members when listing department
  access.

* Add ability to update primary department members role

* Quick staff add - inherit role of the primary department as default role

Use org_id to filter users to update on organization delete

Within this commit, several files got updated to split up strings like "Disable for this team" / "Disable for this department" into "Disable for" and "this team"/"this department".
So a) a little bit less translations and b) all strings of "this (ticket|task|API|canned|FAQ|depart|email|group|site|SLA|agent|team|template|help|ban|category|custom|end user|role)" can match already existing "this ..." translations now.
PS: Didn't remove all that whitespaces in include/staff/tpl.inc.php - seems like my php editor app has done that automatically :/

One s too much here - it's singular and not plural when editing a task

This partially reverts a change in the ORM changing the QuerySet::all()
method to return an Iterator rather than an array. I spent a while proposing
a patch to replace usage of all() with iterations; however, I cannot propose
a valid reason to abandon the previous methodology.

This reintroduces the previous behavior: calling all() will yield an array
of results from the QuerySet's iteration system.

Also, add build version and path information for the PHAR files listed as
language packs.

This pass also makes a stride at adding correct punctuation and making error
phrases consistent.

This is my attempt at removing similar texts from the translator work load.
It also makes an attempt at dropping some misspelled words and works toward
standardizing some phrases.

This duplicates the custom logo code to allow for custom login backdrops. A
new page is added to the "Company" settings page which allows for management
of the uploaded custom backdrops.
