Added link in description to Fix New Twitter stylesheet.
Twitter uses -moz and -webkit prefixed CSS properties, but often leaves out the unprefixed versions that work in Opera (and sometimes includes -o prefixed properties that don't exist). This stylesheet fixes as many of these missing properties as possible and makes Twitter look like it's supposed to.
This stylesheet was generated with my CSS Fix widget with a couple fixes for textbox backgrounds added by hand.
