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.

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

And extend the information to email templates

The typeahead for user email address was dropped somewhere along the way

Fixes #77

If a form field is required, then a name will be necessary in order to plumb
up the API.

Add information about current software versions, server software, php
extensions loaded, and database space usage.

In the future, this will offer a nice place to add an import/export button
for data backup and restore, announcements, and more

Fixes #65

Also ensure that the ticket thread is displayed in a <div> container as some
browsers seems to frown upon <iframe>s in <td> elements

Fixes #75

PHP can't discern the difference between d/m/Y and m/d/Y when just the date
is submitted to strtotime(). Unfortunately, strptime() is not available
until PHP 5.1.0. This patch forces datepickers to change their values to
YYYY-MM-DD upon submission to disambiguate parsing issues.

Fixes #832

Including adding support to the TCL uninitialized variable reader to ignore
class-static variable access as well as detect inline functions and their
closure arguments.

Fixup several minor bugs concerning initial experience

Moved to an initial form which specifies the ticket's priority and issue and
changed the rendering to render things properly. Now the user can decide
where priority shows on the client side, and the priority privacy setting is
placed in the dynamic form wizard.

The standard form is added to every ticket without option. Extra forms can
be defined and associated with help topics which can additionally be added
to tickets upon creation. This allows for standardization of the dynamic
data location for searches and filtering.

Implemented advanced search for dynamic data. Along with reinstating the
basic ticket search on keywords

Implemented ticket filtering on dynamic data for both keyword searches as
well as searches for special fields (drop-down lists, etc.)

Phone number for users is now completely optional

This moves client information like name and email address out of the general
dynamic forms data for a ticket. It really paves the way for the first-class
user of the future.

Previously, form sections were grouped into form sets for reusability. This
patch drops the form sets and makes form sections the new "forms".
Eventually a section-header field will be added that technically does not
add any dynamic data to the form, but allows for the same feature as having
a form set with multiple sections.
