This patch fixes a small glitch where validation might be bypassed for
fields for agents. Previously there was a glitch where required fields would
have their validation errors ignored.

Add other locations as well a failsafe for the htmlentities() call

Editing on preview mode resulted in partially hidden edit form. This fix
adds ability to popup a dialog modal on edit while on preview mode.

Show user search box when adding a new user

Don't show user search box, when adding a new user, if the system don't have remote directories installed

Support searching both staff and user backends via a common interface.

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

If a remote user is found by name and does not have an email address, a bad
SQL query would be generated

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

Requires authentication plugins to implement a new AuthDirectorySearch
interface to define the two functions

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

Fixes osTicket/osTicket-1.8#296

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

Fixes osTicket/osTicket-1.8#281

This includes the initial concept of pluggable authentication along with the
initial concept for a plugin management system.
