[vevo] Some improvements (fixes #1580)

Browse source 
Extract the info from http://videoplayer.vevo.com/VideoService/AuthenticateVideo?isrc={id}
Some videos don't have an smil manifest, extract the video urls directly from the json and use the last version of the video.
Extract all the available formats and set the 'formats' field of the result
