Start of an applet/php hack for showing mote LED status on web pages:

	* www/BlinkenLichten.java, www/BlinkenLichten.class: Applet that
	connects back to the server and changes its color based on output
	from a php page.

	* www/GNUmakefile.in: Install java classes.

	* www/ledpipe.php3: Draft page for driving the BlinkenLichten
	applet, it just alternates on/off and doesn't read the real
	status.

	* www/showstuff.php3: Add a function that outputs the html magic
	to embed the applet.
