Test

For the next test i've created a world with both horizontal and vertical movement.

For now I've only used clouds and stuff like that. I will add land, sea and other things later, but first I want to be able to get images from a external folder so I can add images external and i don't have to put them into the source itself. This makes it easier later on to make the graphics nicer and to put in more graphics. It also works better for making categories of worldtypes (land, sea, air, etc).
