Change thread entry title bar to use more flexible layout using div's and
span's in hopes of avoiding unnecessary wrapping -- especially in the poster
name column..

Fixes oversize image display to be resized in both the ticket thread and
the redactor editor in (at least)

  * Ticket-view boxes
  * Client new-ticket form
  * Staff new ticket
  * Page add/edit
  * FAQ add/edit
  * Canned response add/edit

Fixes osTicket/osTicket-1.8#247

If _SERVER{REQUEST_URI} does not start with a leading slash, add one. This
will ensure that the redirect URL offered after a successful login will
be to an absolute url rather than an implied relative one.

Fixes osTicket/osTicket-1.7#858

Unpack user data for filtering purposes for staff created tickets

- Remove Client form
- Provide name and email fields for cases where use is not selected (JS
issues)

Add ability to change ticket owner on ticket view
Add get last updated date to user class

Fix odd CSS error

The upstream ORM method was removed

without required, internal contact field

Fix duplicate phone number (again)

  * Require a label on form fields
  * Require variable name to be unique per form
  * Fixup duplicate phone numbers on upgrade

Fix width of the ticket thread body
Add consistent font styling between Redactor and thread body

This include URLs in embedded links as well as URLs for external images and
videos embedded via iframe elements.

Also add images on pages to the drop-down list for image choosing, and fix
display of images on the client portal.

Allows the client to be changed on a ticket. Previously, only the
information about the client associated with the ticket was editable. This
patch permits assigning a completely different user to the ticket.

Previously the richtext editor introduced the loss of the collision
avoidance feature.

  * Upgrade to Redactor 9.1.7
  * Use a (x) icon from font-awesome for the dialog

Since the ticket thread is nested in a div now (required for inline videos
to be displayed correctly), the image hover caused the images to be shown at
the end of the thread entry body rather that its original location.
