Support JSHint exlude by filepath patterns

For example I have a unminified file ```irk/static/fileupload/js/lib/app.js```.
But I don't want to include that file into statistics because it is a js library. I trying to exlude such files with pattern ```--jshint-exclude=*/lib/*```
But it is not take any effect, becase ```finder.list(self.exclude)``` checks only filnames without path.
There is my solution for that situation.
