[PD] midi_sync_out

I bet someone has already done this but I haven't seen it yet so I
figured I'd do it myself.  I made an external which lets me send midi
clock, start, stop and continue messages out of pd.  This way I can
sync an external drum-machine, sequencer, etc., to pd.

I've placed the code here:

I just wrote it in the last hour or so, and have tested it only with 1
drum machine.. I'm using ALSA for midi, if you're not you'll have to
modify the Makefile (I couldn't figure out how to send midi bytes in a
generic way as the sys_queuemidimess function is static).

It is a super simple external.  I tried for a while to simply use the
[midiout] object but I couldn't figure out how to get it to actually
output anything.  I looked at the pd source code, it looks like there
is a little bit of code to send clock out messages but I don't think
it is exposed to the user in any object... and I didn't see anything
about start/stop/continue messages.

There is a help file which explains the functionality of the object
and gives a really basic sync out solution.

Please tell me if this works for you, if this is redundant
[encompassed by another project (which you could point me to)], etc.
