[BUGFIX] YouTube videos can not be played with Media CE

Since the rework of the media content element for TYPO3 4.7, YouTube
videos cannot be played anymore using the Media CE. This patch adds
an autodetection of urls which are handled by a media wizard and sets
correct video renderer type.

Tested with youtube, vimeo, myvideo, liveleak
