Detect @import and also CDN URL

[ernilambar]

While I was reviewing a theme I found following in style.css.

Detect CDN import in style.css.

@import url(//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css);

This should be blocker I believe.

Also, may be it would be good to detect @import and recommend theme author to use proper hooks and functions to load styles and fonts.

@import url(http://fonts.googleapis.com/css?family=Arimo:400,400italic,700,700italic);

The cdn.php check only checks the php code, not the CSS files. It should check both.
