Added missing text displayed when the progress engine tries to close the window (from when a user goes back to a previous activity). Only seen if the window fails to close e.g. something goes wrong and we aren't in a popup window.
latest flash compile after resolvign Jira Task: 682 (showing tooltip for the activityies where title is bigger than 19 character and aligning progress bar line to centre )
Removed calls managing the learner in lesson cache - it isn't being used currently and the implementation didn't clear out users who closed their browsers without doing a proper exit.
