JavaScript and CSS are not subclasses of text/x-csrc. Add test files for CSS.

JavaScript is derived from ECMAScript, not C source.
And CSS has no real relation to C source at all.

This patch changes the <sub-class-of> values of application/javascript and text/css to reflect their true parent class.

This also adds two CSS test files (the recommended stylesheets for HTML 4 and an old iteration of HTML5) for increased test coverage.

(I wasn't able to find an ECMAScript sample that wasn't reliably uncontaminated by JavaScript extensions, so that hole in the test coverage remains.)

There's a good reason why they are subclasses:

    * freedesktop.org.xml.in: Patch from Robert DaSilva
    <spunit262@Yahoo.com> to make Javascript a sub-class of C sources
    so as to avoid misdetection
    * tests/list:
    * tests/survey.js: Add test-case from the bug above

Did you check that your patch didn't break the test suite?

It's not clear to me where the misdetection was occurring—on the C side or the JavaScript side? Either way, this doesn't revert that change directly; it changes JavaScript to be a subclass of application/ecmascript (which it is), not text/plain (which it was listed as before being changed to text/x-csrc, which it isn't).
