Sky client

Thanks to the work of quite a few people, especially Emajekral and Schmurk, now we have a sky dome, and a much larger viewing distances and viewing angle.
Everyone is very happy with it, and we hope to make it the next official client. There are some more tests to be done, but things are coming up nicely.

People with slower machines might have to use the 'standard' mode, where the camera angle is limited, but they will still benefit from the new light colors, which are much better than what we used so far. For example, the light color changes at dusk and dawn.

It is really amazing to see how much our little game evolved. Here are two screenshots, the first being about 5 years old, and the second is with the new client (pre release).
