Moves the starting point to a randomly-selected location before the Player object is created. A single starting point is created as normal. From that point, create ScriptParams links to markers at the other locations. One of the links can be to the actual starting point to consider its current position as well. Each ScriptParams link has the data Startdiff, where diff is the difficulty levels that the link is valid on. 0 is easy, 2 is hard, 012 will work on all difficulty levels. When Sim starts, the starting point will be teleported to the destination of one of the links.
