[GREENFOOT-237] Exported jar window can be resized
Currently when exporting a scenario to a Jar file, the window can be resized \- is this the desired behaviouor? Resizing just hides some of the world or creates a huge grey border, and seems a bit illogical when the world itself can't resize basd on the window size.
