scsynth doesn't support command-line arguments other than UDP port

[nhthn]

Again, I'm on Ubuntu 16.04, launching scsynth with the below code:

var sc = require("supercolliderjs");
sc.server.boot({
    scsynth: "/home/nathan/usr/local/bin/scsynth"
});

SuperCollider launches successfully and I can play Synths with it. However, it doesn't connect to the system inputs and outputs in JACK, as can be seen in this Patchage screenshot:

It's also odd that it has eight inputs and outputs, when the default supercollider.js settings have numInputBusChannels/numOutputBusChannels both set to 2. It looks like the command-line arguments to scsynth are getting dropped somehow.

Ah. Args other than the UDP port are not implemented. Is there any way I can hack around this?

I should implement them ! And provide a way to add arbitrary ones in case the api gets out of sync.
