BUG= https://code.google.com/p/dart/issues/detail?id=18508 * tests from https://github.com/w3c/web-platform-tests/tree/master/selectors-api, kept as close to original as I could. * src/query_selector.dart is most interesting file. It implements enough of selectors to pass the basic web platform tests. Ironically, it was the easiest part of this CL... * many fixes to csslib. Almost all of the selector tests were skipped (https://github.com/dart-lang/csslib-test-suite/blob/master/suite/selectors3/selectors3_test.dart) and there was a lot of things broken: unicode, escaping, incorrectly treating ident-tokens as units, probably more that I am forgetting :). Fixed as much as I could without doing major surgery. * a bunch of fixes to the htm5lib DOM to bring it closer in alignment with dom.spec.whatwg.org and dart:html. The driving force was to minimize the changes needed on the W3C tests. Note: haven't updated things that depend on html5lib like Polymer yet.
