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

The change will allows staff to open a new ticket without going through the
"forced" user lookup popup. On cancel the staff is presented with a
simplified user info form with email and name being the only fields
required.

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

Arrange templates in a group by their respective use in the system:

  * System Management Templates
  * Staff Ticket Templates (Alerts and Notices)
  * End-User Ticket Templates (Autoresponder)

This provides an interface to sort the templates and make them easier to
find and provides a nice place for new templates to be added without making
it increasingly more difficult to locate templates in the list.

This patch also fixes the missing templates in the drop-down list when
editing an implemented template.

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