Pattern for CSS url() syntax matches wrongly also some JS url() function calls

[florianheinze]

In the discoverRegex patterns, the /\s?url\([^"'].*?\)/ig has a dot too much.

If there is e.g. JavaScript code like foo;url();bar();doo the pattern matches url();bar(). The reason is that the [^"'] consumes already the first ) closing bracket in the haystack, and so the following \) has nothing to match anymore.

A simple fix is to strip the . and just use the [^"'] as our wildcard, like /\s?url\([^"')]*?\)/ig.

This problem can lead to crawling URLs with strange JS code appended to it. Like http://example.com/%29;bar%28
