        * gimp-lib/rubyfu.rb: Removed some unnecesary code. Clicking 'cancel' in
          the dialog will now work correctly. Interactive procedures that take
          no parameters don't trigger the dialog.

        * ext/rbgimpdialog.c: Added a enumeration popup widget. show_dialog()
          now takes an extra parameter for the menu name. The procedure name
          is used as the help_id, and the menu name is used in the dialog title.
          Parameter names now have a ':' appended to their labels.

        * plug-ins/test.rb: Added the new parameter type.
