Moved the parsing of media query lists to the CSSParser where it belongs (rather than regular expressions). Please note that media queries are not yet working because we have to add a token to the lexer(LPAREN) and rerun the lexer generator. That will be in the next commit.
Reran lexer maker (JFlex.de). Media queries still are not working!
YEAH! The parser is now correctly parsing media queries. Evaluation of media queries is not yet complete.
Added some unit tests for parsing of media queries.
