Previously we required an account to associate a user to an organization.

Useful if the staff members administratively configure a static password
that the user should never change.

Deleting an organization with users will simply orphaned the users.

This is necessary so we can use the templates to show tickets assoaciated
with user as well as organization by simply switching the context.

Change z-index to overlay popup windows correctly

Show ticket prview when a ticket number is clicked as opposed to ticket
view.
Add collaborator preview tab on ticket preview tool tip.

Previously you had to click "Save Changes" for the count to be reflected on
ticket view page.

Fixup search for users with hits in an searchable authentication backend:

  * If there is a hit for the remote backend, include that in the search for
    local users by email address. If there is a hit locally for the same
    email address, then remove the remote hit from the search results.

Fixup typeahead results

  * Abort previous search requests when the user enters more text into the
    search fields. This makes the search box feel more consistent, and
    avoids the case where the user finishes typing and valid search hits
    never appear

And define getInitials() function for %{ticket.name.initials}

Displaying field values on various pages and dialogs could result in cross
site scripting exploits.

Fixes osTicket/osTicket-1.8#296

Previously only the name, email, and phone number would be displayed on the
pop up dialog

Previously, the user information could only be modified on the ticket-view
page. For instance, if creating a new ticket for a user, no new information
could be added or modified on the user until after the ticket was created
