Title: Filter Out Regions from Layout.$

In some cases a developer may not have any knowledge of a how an application was assembled or have full control over the modules on the page. This is happens frequently in large composite applications. This pull is a prototype for optionally filtering out region views in a layout view when .$('some selector') is called. This helps prevent a developer of one module's view from unintentionally impacting another developer's module view.
