Some jolly and worthwhile additions. Serial connections now work, though
I'm positive it's not a very clever way of doing it - kind of a kludge
between the processing way and the java way of doing things, and perhaps
the worst of both worlds, but we'll see. Added new class to roll up
incoming event handling stuff. Nothing that actually _sends_ commands
yet, but at least they're talking now. Had to suppress an irritating NPE
to do with the serialEvent method in the PApplet example. Think I am
missing a point here somewhere.
