- Also updated readme and removed unused sfml-network dependency
- Remove redundant inclusion of /opt/local library search paths, as my Boost is in /usr/local and trying to compile against the MacPorts version doesn't work for some reason
- Use absolute paths instead of relative paths for linked frameworks and libraries in the project structure
- Don't try to link SFML.framework as it only contains headers, not libraries
- Add freetype to the project (was always a dependency, just more explicit now)
