Remove preview widget from GtkFileChooser

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

- * 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.
