BeginUmbracoForm working for both local and plugin SurfaceControllers. SurfaceController class now inherits from PluginController which exposes all things a dev would need including making IPublishedContentStore and IPublishedMediaStore public which can be accessed simply by properties on the controller. Updated web.config for views to include Umbraco.Web namespace for all of our helper methods. BeginUmbracoForm now has many more overrides for which you can specify a type or a generic type (we no longer require GUIDs :)
