    Avoid API breakage of GMimeParserWarning (#42)
    
    in 14671817dc1a64d8840b2f612cd143f29d55ecbf,
    GMIME_WARN_INVALID_PARAMETER was introduced, but it also changed the
    enum values for every GMimeParserWarning that followed it in the list.
    
    This means that if someone built against a prior version of GMime and
    then upgraded their library, the library might try to return, say,
    GMIME_CRIT_CONFLICTING_HEADER but the application would interpret it
    as GMIME_CRIT_CONFLICTING_PARAMETER.
    
    This change restores the original API for GMimeParserWarning, since
    there is probably already released and distributed software built
    against the older header files.
