Implement format selection in YoutubeDL
Now the IEs can set a formats field in the info_dict, with the formats ordered from worst to best quality. It's a list of dicts with the following fields: * Mandatory: url and ext * Optional: format and format_id The format_id is used for choosing which formats have to be downloaded. Now a video result is processed by the method process_video_result.
