OK, the new Ur/Web release works for me in the latest Firefox.  I'm 
pretty confident that it's a Firefox bug that caused the trouble, but 
I've changed the compiler so that that sort of bug shouldn't cause 
trouble in the future.

I have no idea how to deal with this, and it's infeasible for me to test 
anything on a Mac, so I'll ignore this for now.

Thanks.  I've changed the compiler to avoid self-closing tags that 
weren't traditionally self-closing in HTML.

I'm going to ignore IE for now, since I want to prioritize developing 
case studies that demonstrate why metaprogramming is nifty in Ur.
