SFML and Eclipse

Giving Eclipse another shot to see if it could replace Netbeans as my IDE for C++, I wanted to see if I could compile the server for my Gaoth project. Since MinGW already was installed, it found and chose it as the default compiler, which was great. It was, however, when I tried to link in SFML that I got into some trouble as it was very unclear of how it should be done.
