Subject: [PATCH] Add Support for streams from Nanocosmos

Add a full nanocosmus stream URL.
The URL has to include: "nanocosmos.de"
the ID will be extracted by looking for an equals symbol.
So: something.nanocosmos.de/somethingelse=1234-5678

will detect 1234-5678 as videoID.
The iframe that will be used is fix.
