Maps Redux

The home page now displays an up-to-date map showing where everyone who's ever taken part in one our projects was born. I'm a little unsure about the placement of some of the dots (especially in Ukraine and China); corrections would be welcome. As you can probably tell, I went with Google Maps in the end. This wasn't because Yahoo Maps or any of the other sites I wrestled with couldn't do what I wanted; instead, it came down to which was better documented. Let that be a lesson to students, and to those who think it's code that matters most... ;-)
