* Options can now be passed to aposSingleton and aposArea, which ultimately reach the templates for the widgets, as well as the javascript for the widgets. aposArea's options should be grouped into properties by widget name. This is tested for singletons
* /edit-virtual-singleton implemented. Provides a singleton edit button in a pure browser side javascript context in which storage is provided by the caller (in other words, we can now have singletons in snippet forms)
* Nested widgets due to reuse widgets (like the snippet widget) do not cause problems in the editor
* Limit option for slideshows
