Fixed issue with another test... no idea how it didn't show up failing before.
Fixes issue with string extensions and an infinite loop when the string to strip is empty/null.
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 :)
