Title: Using correct journald fields, mapping priorities, sending defaults.

This updates the winston transport to use the correct ```MESSAGE``` field. Additionally, this adds the ability to specify default key/value pairs on transport creation (i.e. SYSLOG_IDENTIFIER), and attempts to map the `level` string passed by winston into a numerical value for the journald PRIORITY field.
