Even more great updates for GRUNND!

I was not sure whether GRUNND needs it. But in the end I decided YES. With this update GRUNND gets an option to manually Save and Load games via two optional slots. There will be always an AutoSave - it will not go anywhere, but this extra flexibility, if you needed one, will make playing GRUNND more enjoyable. Also updated Ending a bit, and some small fixes I don't even remember. Should've written those down. Also yesterday sent out keys to our BETA testers, who participated in testing during December. Update the installation! - Olafs @ GRUNND
