Unleash the power of 3D

Linux versions for Bforartists 2.4.0 available

We had some trouble with our linux versions. So it took a bit longer this time. Sorry for the inconvenience. And thanks to naetherm for the fixes.

Now everything should work as expected. The rpm and deb version does however not work at Ubuntu 18.04. It is compiled with Ubuntu 20.04. And will throw an error. Please use an actual Ubuntu version.
