fix support to gorillavid.in

[kpgx]

Some links doesn't seem to work,
Example url http://gorillavid.in/7unblsdg8bcz

It looks like gorillavid has started requiring explicit user interaction. We'll need to add explicit support for it (so far, the generic extractor picked out the video). However, it looks like the URL in question may infringe copyright, based on the filename. Can you name a URL that does not infringe copyright? As a matter of policy, youtube-dl only supports non-infringing services.

This URL doesn't infringe copyright. But also it doesn't need user interaction. Will this suffice?

That URL works fine already:

$ youtube-dl http://gorillavid.in/q3weqgtkkwfe
[generic] q3weqgtkkwfe: Requesting header
WARNING: Falling back on generic information extractor.
[generic] q3weqgtkkwfe: Downloading webpage

[download] Destination: GorillaVid - Just watch it!-video.flv

I'm closing this issue now, but feel free to mention a non-infringing URL that needs to be supported and we'll reopen it.
