v3.1.0

v3.1.0 (Enhancements by @derrell)

• Refactored qxl.dialog.Dialog and qxl.dialog.Form
  • The mass of functionality for Dialog and Form now resides in
    mixins, MDialog and MForm. The MDialog mixin is included by two
    classes, Dialog and DialogEmbed; and the MForm mixin is included
    by two classes, Form and FormEmbed. The Dialog and Form classes
    work as they always have, creating a pop-up window in which to
    render. The new DialogEmbed and FormEmbed classes allow forms to
    be placed in any arbitrary container of the programmer's choice,
    so that these classes can be used for the main functionality on a
    page rather than only as pop-ups.
  • It is now easy to extend the Form functionality (both windowed and
    embedded) with form elements that are not provided as part of this
    package. All form elements, including those provided with this
    package, are now registered in a standard way. This means that
    user applications can register form elements not provided by this
    package, and include them in forms created using this package.
• Added a generic multi-column form renderer, and the ability for an
  application to easily provide its own form renderer.
• Arbitrary propery settings can be provided to any form element.
• Arbitrary events can be handled from any form element.
• Arbitrary userdata can be specified for any form element. This is
  used, within this package, to specify row and column numbers for the
  multi-column form renderer, but it can be used for any other
  application needs as well.
• A finalizeFunction can be provided, which will be called when a
  form is completely generated. This finalize function may be used at
  the application's discretion, but in particular, it allows the
  application to add validation to the complete form, that requires
  that all of the form elements have been added to the form.
• Access is provided via the _formElements map, to all of the form
  elements. The map is keyed by the same keys provided in the
  formData map.
• beforeFormFunction, afterButtonsFunction, and
  afterFormFunction allow widgets to be added above and below the
  form, e.g., headings, or buttons that act on the form.
• Fixed the non-functioning labelColumnWidth
