Removing the "Act" node from the activity tree. Fixed the tree to take the isvisible default as true. Showing the "select resource" message only if there is more than one resource.
Fixed several problems: Removed play from activity tree. Activity tree doesnt show activities with no "visible" property anymore. Removed filename from environment resources. Fixed issue that allowed some property groups to be created twice.i Monitor screen is shown within the content div now. Made the admin page to be valid HTML. Changed button label from "Exit UoL" to "Finish".
