Can't seem to create t:ANIMATECOLOR element by using document.createElement. Also tried createElementNS, but IE8 has this weird behavior of createElementNS not kicking in consistently, which ends up causing a "Object doesn't support this property or method" error.  This problem has always been reported by other people in the past: https://code.google.com/p/svgweb/issues/detail?id=625

I ended up using innerHTML to get around that, but this may mess with the exploit, so use with caution.
