Widget Show / Hide Options

Most GeoDirectory Widgets contain the Show / Hide Options pictured below. 

GeoDirectory uses WordPress pages as templates for most main content.  This lets users edit templates with no coding knowledge and it also means most GD templates will use the same widget sidebar as normal WP pages out the box. [@TODO see how to add a new page template just for GD templates]

Given that several GD widgets may be used on several different page types, the Show / Hide Options let the widget output be limited to specific pages only.  Therefore, you can add a map widget to the sidebar but have it show on the GD single pages only.
