OZP-806 Added the ability to handle the windowname=true parameter for OWF7 Legacy REST requests. Added a JAX-RS MessageBodyWriter for the "windowname" content type. Uses patterns from OWF7's OwfBaseRestController.
OZP-806 Added some documentation. Removed the extra debug messages from the window name HTML document to save bits over the wire
