please improve error handling for unsupported site

[leggewie]

It would be nice if youtube-dl did better than simply crash like this. The error should be caught and a more meaningful message displayed to the user that the [site](http://www.handelsblatt.com/video/dirk-muellers-cash-kurs-rocket-internet-und-die-neue-new-economy-blase/10753844.html site) is currently unsupported.

The error should be caught and a more meaningful message displayed to the user that the site is currently unsupported.

youtube-dl currently already does this, though.

As @hotdogman has said, update youtube-dl (see our FAQ if you have any problem).

Indeed, that works. Sorry about the noise.
