Add the Widget macro. This enables assets to be widgetized (easily embedded in

another page). Usage as such: ^Widget(assetId, width, height, templateId);
assetId is the ID of the asset to widgetize, width and height are the size of
the iframe, templateId is the template ID of the template to use for the widget
itself. This will pop up an icon that shows you some markup to put on another
page to embed the asset in widget form. If no template given, will use the
ajaxInlineView of the asset.
