Put in a test jpg and loaded in a texture for the first time.

Now onto creating the ground plane.
Added in the rest of the skybox, and swapped textures.

Now I need to change the textures and actuallt see if this works, and
then scale out the size of the skybox and where the ground plane
originates.
Texure swapping worked, but the sky planes needed to have thier sizes changed according to far they were from each other

Add in an offset for the ground plane (and sebsequently the other
planes) so that the roller coast isn't too far from the ground.
Made some changes to the textures, and cleaned up my file system a little.
Made some minor changes to the skyBoxSize and the track.txt doc
