SVN commit 993552 by rivol:

- Readd space rendering. It doesn't procedurally render a sun and its halo anymore. \
Instead, it now renders  a starfield, using a space texture mapped to a cube. In the \
future this could be extended to use cubemap so  that arbitrary background become \
                possible.
- Add a small program that generates the starfield texture by just distributing a \
bunch of points with random  position, size and intensity.
