    Reorganize Python events documentation
    
    This slightly reorganizes the Python events documentation.  It hoists
    the "ThreadEvent" text out of the list of events, where it seemed to
    be misplaced.  It tidies the formatting a little bit (adding some
    vertical space for easier reading in info), fixes a typo, adds some
    missing commas, and fixes an incorrect reference to NewInferiorEvent.
