    [ SPEC / BUG FIXES ]
    - favour -content-type arg in header if -type and -charset options are also
      passed in (GH #155, thanks to kaoru for the test case). this change also
      sorts the hash keys in the rearrange method in CGI::Util meaning the order
      of the arrangement will always be the same for params that have multiple
      aliases. really you shouldn't be passing in multiple aliases, but this will
      make it consistent should you do that
