Directory File Source

This release adds a new Directory file source. This can be used from the library with gengo::Directory, and activated in the CLI with the -d or --directory flag. This file source is currently considered to be in beta status, and may be missing features that would make it user-friendly. Feature requests and bug reports would be highly appreciated.
