[GREENFOOT-112] It should be possible to 'Get' objects into the world from Inspector/Method result
When a method result is an Actor, the 'Get' button in the result dialogue should be enabled, and it should be possible to place that actor into the world.
Probably this should only be the case if that object is not already in the world.
Same for Inspector.
