Matthew Barnes 01e2fc5b5a Bug 596428 - GtkAssistant: Support ending with a progress page 
- Add gtk_assistant_commit()

  This function discards the visited pages list so the back button is not
  shown on the current page, and removes the cancel button from subsequent
  pages.  Use this when information provided thus far cannot be revisited.

- Don't show the Forward button on a GTK_ASSISTANT_PAGE_PROGRESS if it's
  the last page (according to the forward page function).

- Append a progress page to the GtkAssistant demo.

*
* A #GtkAssistant is a widget used to represent a generally complex

* and controlling the page flow to collect the necessary data.
*
* <refsect2 id="GtkAssistant-BUILDER-UI">

* <para>
* The GtkAssistant implementation of the GtkBuildable interface exposes the

* To add pages to an assistant in GtkBuilder, simply add it as a
* &lt;child&gt; to the GtkAssistant object, and set its child properties
* as necessary.
