Users with edit permission should be able to change ticket owner in line.

Join to staff/user tables to get current name when fetching thread entries.

Include collaborator tickets on search by user.

The concept of extid is being retired to pave-way for customizatable ticket
numbers.

HTML does not allow nested <p> tags. Therefore the user warning was not
correctly hidden with the rest of the user change confirmation message.

Replace phone number on ticket owner update

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

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..

Unpack user data for filtering purposes for staff created tickets

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

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

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

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.

*This is a major redesign / rework of the osTicket base*

This patch drops the concept of static ticket metadata and allows for an
admin-configurable arbitrary data that is attachable to tickets

The system is architected such that the base osTicket install now comes with
a "default" form that has fields for subject, name, email, and phone number.
This form is editable to allow for the addition of arbitrary other fields;
however, the basic fields must remain in order to be associated with a
help-topic and attached to a ticket.

This concept can be expanded to allow for arbitrary data associated with
registered clients or ticket thread items.

Forms are comprised of sections. Sections have a title and instructions
properties and a list of fields. Fields have various implementations to
represent different data such as text, long answer, phone number, datetime,
yes/no, and selections, and are configurable to define the look and feel and
interpretation of the respective form field.

Dropdown lists are represented as "Dynamic Lists", which are
admin-configurable lists of items. Dropdowns can be optionally represented
as Bootstrap typeahead fields.

This also adds the start of a simple ORM which will hopefully be expanded in
the future to support multiple database platforms. Currently, only MySQL is
implemented.

Process inline attachments in thread entry and support inline images in
piped emails

Support inline images across the system, with draft support

Migrate to a single attachment table
    That way we don't need a new table for everything we need to attach an
    inline image to (like a signature, for instance)

Add richtext support for internal notes

Implement images on site pages

* Image paste in Redactor
* Make non-local images optional
* Placeholder for non-local images
* Fix local image download hover
* Don't re-attach inline images

This is safe now, because the title is appropriately encoded in
class.thread.php/ThreadEntry::create()
