A large rewrite, with greater detailed definitions.
*BREAKING CHANGE:* winston.Transport and winston.Logger types have been
renamed to winston.TransportStatic and winston.LoggerStatic
respectively. Instantiating the types still uses the old syntax: ```var
logger = new winston.Logger``` but the return type's name has had
"Static" appended.
