Pause World Class

A world class that displays the visual state of another by drawing the calling world's background image and all its actor images on its background in the proper paint order.

Just click on the world to toggle between the 'Go' world and the 'Pause world. A message panel was added to show paused state and a restart counter was added to time the restart after click.

The code also has an example of placing a random number of actors in the world, while randomly choosing the type of actor to add (without using a bunch of 'if else's or a 'switch').

Have any couse to use: -if(getX()==0 || getX()==getWorld().getWidth()-1) changeDirection(); and not: isAtEdge/atWorldEdge?

@Nahquin, the scenario was written in 2013 -- before the isAtEdge method was a member of the Actor class.
