Update to Web Studio and Web Client

- added WebStudioPreviewURIService and a -context.sample file to enable Web Studio as a preview server for WCM (this is not enabled by default)
- lots of updates to components in app library (to be renamed samples)
- many fixes to drag/drop page assembly
- spice up the UI a good bit
- knock off remaining bugs for Labs 3C launch
