New Copy of Test Suite on W3C Site

Heya everyone,
Bert just posted a recent build of the CSS2.1 Conformance Test Suite
at http://www.w3.org/Style/CSS/Test/CSS2.1/current/ . We're planning
to set up a cron job to update it nightly, I'll send an update when
this happens.

Some of the major changes include:
   - change in directory structure: each output format gets its own
     directory.
   - index page with updated description and a list of assumptions
   - by-section index of all tests currently in the test suite

Let me know if you notice any problems~
