Cross domain CSS files with ? in URL won't load

[jasonreposa]

We use a cache buster variable to force the loading of new CSS. The respond-proxy.html file has a faulty regex that expects .css to be the last part of the string.

E.g., the stylesheet:

http://www.example.com/style.css?1234

Will attempt to load cross domain, using:

http://cdn.example.com/proxy/respond-proxy.html?url=http://www.example.com/respond.proxy.gif&css=http://www.example.com/style.css?1234

Notice the double question marks.

We had a similar issue with compressed assets. Our are .css.gz, sometimes. For now we just hacked the code in the HTML, but maybe there's a cleaner solution?
