    Have Config's save() make directories it needs
    
    Honestly it's always bugged me that write functions don't do this. Oh,
    directory foo doesn't exist? Then... umm, make it? I understand you gotta
    treat computers like a brain damaged infant but come on. It's 2016. Why
    don't standard libs have a reasonable default.
    
    </rant>
    
    Anyway, having our save() method do the sane thing.
