#721 fixed up the containers and containerConnect directives so they actually work
fix to ensure that the modal dialog doesn't accidentally leave a modal backdropy lying around which totally borks the web page after its closed ;) So add an extra check to see if its there and if so remove it (and log a warning that we're doing so - that thankfully only occurs when the wiki page's content invokes the dialog via the fabric-container-connect directive
#721 add better logging so we can see what URL is actually going to be used when we connect remotely
