changes in this commit courtesy of a pull request from the Mark Eats Fork, used in [Mark Eats Sequencer](http://markeats.com/sequencer) :: MIDI messages have timestamps- these timestamps are passed to the MIDI server, and may be used to schedule MIDI message dispatch in the future :: alternate bonjour/zeroconf service names may be specified, allowing you to browse OSC devices or apps not made available under the conventional OSC service name
