Designer:

- Now supports the exit command, prevents the designer from crashing.

Runtime:
 - Added a GUI based set of buttons for traversing your environments via a click-through method instead of forcing users to type commands.

Engine:
 - Added the Exit command to exit the runtime (At this time it shuts down the Designer as well.)
