CSFML and SFML.Net have moved to their own repository

[Laurent]

Here:

- https://github.com/SFML/CSFML

- https://github.com/SFML/SFML.Net



There's only one branch, master, which matches the master branch of the SFML repository. This means that CSFML 1.6 and SFML.Net 1.6 are not available on their repository (but we don't care since the 1.x branch has not evolved after the 1.6 release).



SFML.Net is self-contained but CSFML still requires SFML headers and libs to be installed somewhere. I don't add them to the repository as an extlib, it would require too many precompiled versions (x86/x64, vc++/mingw, 2005/2008/2010, 3.x/4.x, ...).



Both bindings now have their own task tracker on github. Everything else remains available on the main website/forum, nothing's changed.

I've also removed the D and Python bindings from the main repository, I've tagged the corresponding revision so that interested people can easily find their latest revision.
