Add public constructors to gesture tutorial fragments.

The lack of public, no-arg constructors was causing the tutorial to crash on re-creation (eg. rotating the screen.) Added public constructors and refactored event logging.

Also added an update to the All Set page to allow the subtitle to display in one line.
