[visir] Complete rewrite of the visir information extractor.
- Articles are handled by VisirArticleIE, the media sites by VisirMediaIE. - The video m3u8 playlist is retrieved from a json playlist, but unfortunately this does not always word, e.g. http://www.visir.is/kaup-thriggja-risaskipa-styrkja-tengsl-islands-og-graenlands/article/2017170129275 - A better way to do it, is to mimic the javascript code from the visir embedded video site, e.g. http://www.visir.is/section/media/?template=iplayer&fileid=SRC38BFD200-8465-4A46-9F2A-342E613568E1
