The test now doesn't fail anymore. It just checks the string for having
"vimeo" in it, instead of using the method for URL-checking, since it's
returns an error.
The tests don't fail, and the extractor works fine now.
Quick and dirty fix for the Gamekings extractor. It gives an error about
the video_url, but it downloads it now instead of giving a 404 error on
newer Gamekings videos
When trying to download some GameKings videos, not all worked. This was
because not all videos had a "/large"-URL available. The extractor
checks now if the /large URL is available, if it isn't, it tries to get
the normal URL.
