I have changed the spec for hashless hex color and unitless length to be  
closer to reality (I hope). I have limited the them to the properties in  
CSS2.1 that have colors or lengths but aren't in the list above. I made  
"support hashless hex colors" match IE instead of the other browsers,  
since IE was stricter (even in compat view). I still haven't figured out  
'font', but I'll get to it.
