Parser breaks when an end parenthesis occurs in a quoted string

[papandreou]

require('cssom').parse("body{background-image: url(')');}")

Output:

Error: Unmatched ' (line 1, char 30)
    at CSSOM.parse.parseError (/home/andreas/work/CSSOM/lib/parse.js:54:15)

It's caused by parse.js handling ( in a CSS value in a rather naive way: index is advanced to the first occurrence of ) regardless of whether that's inside a quoted string, eg. url('...)') or url("...)").

The error occurs "in real life" with this file: https://github.com/ajaxorg/ace/blob/master/lib/ace/css/editor.css#L305

Similar example that throws error:

 .foo {-ms-filter: unqoute('alpha(Opacity=75)');}

Fixed for:

body{background-image: url(')');}

http://nv.github.io/CSSOM/docs/parse.html#css=body%7Bbackground-image%3A%20url(')')%3B%7D

.foo {-ms-filter: unqoute('alpha(Opacity=75)');}

http://nv.github.io/CSSOM/docs/parse.html#css=.foo%20%7B-ms-filter%3A%20unqoute('alpha(Opacity%3D75)')%3B%7D

I haven't done any real-world testing. Please let me know if I broke something.
