[General] wiki broken? -and java lively

Hi Peter -

Hmm.  All works fine for me in Safari, FF3 and Chrome, starting at...
	http://livelykernel.sunlabs.com/repository/lively-wiki/index.xhtml
and testing the kaleidoscope as well.  (not what you wanted to hear I know)

Usually scratch.js gets ignored without mishap.  What browser are you using?
Any possibility that something wrong is being cached?  Make sure
all caching is emptied and off at least once.

This is great to hear!  Up to now, the only way we had to hook up
to Java was Krzysztof's somewhat special hookup though emulated DOM.
Would be great to have this work along with midi for the PianoKeyboard ;-)

Indeed.  You go, guy...
