Doesn't open on Windows because ports are labelled COM, not tty

[anotherdave]

Hi, loving your work on this with mtxcontrol. Just a couple of minor tweaks:

Under Windows COM ports are skipped in initPort because the code checks for "tty". Fix in Rainbowduino.java:

        if(PApplet.match(ports[i], "tty|COM") == null) continue;

cool, thx, I'll consider it with next release...
