`extract_info` now expects `ie.extract` to return a list in the format proposed in issue 608.

Each element should have a '_type' key specifying if it's a video, an url or a playlist.
`extract_info` will process each element to get the full info
Add auxiliary methods to InfoExtractor to set the '_type' key and use them for some playlist IEs

The calls with the message starting with 'WARNING' have been changed to report_warning instead of report_error
When a redirect is found return the new url using the new style
