Disable autoquoting of resolved urls

@SharkHunter: finally got back to this :) and noticed in unix quotemarks are being passed literally and cause ffmpeg to fail with "file not found".  As far as I can tell removing them has no adverse effects in Windows either. The purpose of the second commit is just to improve logging. Next jumpy will include an xbmc resolver.

Update: no need to exclude unresolved youtube urls any more.
