Remove preview widget from GtkFileChooser

Browse Source 
The preview widget harks from a platform before time, when we didn't
have GIO, or a thumbnail specification.

Very few applications use it correctly, if at all; it has an horrid hack
to deal with the ownership of the widget's instance when accessed
through the getter function; it messes up the layout of the widget and
its label is less than useful when it comes to file names longer than a
dozen characters; it's a poor substitute for a proper thumbnail view.

* # Adding a Preview Widget
*
* You can add a custom preview widget to a file chooser and then
* get notification about when the preview needs to be updated.
* To install a preview widget, use
* gtk_file_chooser_set_preview_widget(). Then, connect to the
* #GtkFileChooser::update-preview signal to get notified when
* you need to update the contents of the preview.
*
* Your callback should use
* gtk_file_chooser_get_preview_file() to see what needs
* previewing. Once you have generated the preview for the
* corresponding file, you must call
* gtk_file_chooser_set_preview_widget_active() with a boolean
* flag that indicates whether your callback could successfully
* generate a preview.
*
