Little fixes on the Klezmershack
As I stumble towards making the KlezmerShack useful and working again, have addressed a couple of technical issues. "Search" works again, although since I last added Google search code, I see that the results now include Google ads. Will keep my eye open for a good search that avoids that. I do happily carry ads, but I want to make search work better, not put more stuff in the way of people looking for results on the Klezmershack.
I have also made the KlezmerShack work with current web security. This never mattered in one sense—there was nothing on the KlezmerShack that needs to be encrypted for anyone but me, as the maintainer. But it will make browsers happier when they visit the site, which is probably a good thing. Let me know if you spot problems.
