Forest World target times

I would have done a pull request, but I cannot do git stuff on this computer. I think a level is missing anyway. Add it if you wish, or modify the times if necessary. Here are the times in seconds pasted.

You could, technically, edit the files using the github gui, couldn't you?

@tobbi This doesn't make sense now anyway, since many of the Forest levels are currently at the risk of being deleted. This should wait until we have a more or less stable Forest World.
