- [Unix] Removes gratuitous case mangling of the case, since \*nix-es are
usually case sensitive, so mangling is not wise

based on XDG_DATA_DIRS and make room for respecting the standard which
specifies XDG_DATA_DIRS is a multiple-value variable
- [Issue 6] Add ``*_config_dir`` which are distinct on nix-es, according to
XDG specs; on Windows and Mac return the corresponding ``*_data_dir``
