Call passon to update the progress bar on tool pages, optional activities and the completed screen. Should also cope with the user partially doing an optional activity, continuing on in the design, then coming back later to the optional activity to do more, and then going back to where they were up to in the sequence before jumping back.
Added "exitted lesson" screen and I18N'd the text of the welcome screen. Made the Action more robust with respect to exceptions - most exceptions are now caught and a proper error message is sent back to Flash (rather than nothing being returned). Changed the LearnerActions to not forward to page when the wddx packet is returned. We now have a Flash interface so forwarding to a page (rather than letting Flash bring up the next bad) is now bad. Had to change the dummy learner screen to still forward temporarily otherwise the dummy screen won't display the tool pages.
