Fixing the individual reports so they work if only the activity_id is provided. Adding messages to know whats going on during the import of the UoL. Changing the show/hide panel icon for a more proper one.
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".
