Update repo address
Fix wiki link

GitHub keeps changing how relative links work in repository readmes - which is troublesome. I don't want to hardlink it because it should point to the wiki on people's forks (if they have one) and there is already a hard link to this repository.
Changes to how configurations are loaded.

Configuration checks working directory for a config.json file. If none exists (the working directory is somewhere it shouldn't be), Configuration looks at the absolute executable path for config.json.

Program can now be launched from another directory with a different config file for testing purposes.

boost_filesystem is now required for the project.
made exe_path static
