Playback: dump all relevant info over OSC

Hi,

I have a feature request that would aid me immensely to connect several standalone programs and allow for easier hacking and extension of musescore:

When running playback, musescore should dump all its current playback information over OSC in real time.

I am thinking of something along the lines of how Sibelius organizes its playback hierarchically and allows to fall back to standards of the specialized version does not exist. Say a violin is currently playing a bartok pizzicato on E +quarter tone, the OSC message could look something like this: /musescore/playback/64.5/instrument/strings/violin/pizz/bartok/ (64.5 represents the MIDI value for E (64) with a .5 to indicate a quarter tone step up).

A dynamics change for an specific instrument (e.g. our violin above) could look like: /musescore/playback/64.5/instrument/strings/violin/dynamics/mf - or, could have a user defined range between e.g. 0. for ppp and 1. for fff: /musescore/playback/64.5/instrument/strings/violin/dynamics/0.65 (which would also allow good control of e.g. crescendo +similar in real time)

Of course, all control data, for example tempo (/musescore/tempo/120) or practically any symbol (/musescore/symbol/clef/treble, /musescore/misc/bar) could even be sent. The whole score can be translated into OSC messages, which can prove highly beneficial for hackers and developers to potentially create amazing ideas.

I for my part have IRCAM's Solo Instrument library, which I would like to hook up to musescore, specifically *only* for the extended playing techniques that I cannot find anywhere else, but currently have no idea how to mix this with other playback methods...
