Fixed issue where error message was shown every time the user chose to move continue using the keyboard.
Fixed issue where data wasn't saving to file after questionaire.
Changed SubjectData output filename to "<Participant ID>_qu.dat" (previously was "subjects.dat". Would have been overwritten as wasn't dynamic.
