- "hls" prefix now refers to Video Factory streams. Old HLS streams now denoted by "hl" prefix. - Removed old method of finding HLS live TV streams from HDS data. Live TV streams now derived from Video Factory data - force "hls" prefix for audiodescribed versions (not in VF data) - sort modes for --info display - force ffmpeg -loglevel error for video Closes get-iplayer#190 Closes get-iplayer#202 Closes get-iplayer#205

Carry on from #178 and add support for Video Factory HD streams. Those streams are different from previous HD streams. There are two streams: 960x540/50fps/2800kbps and 1280x720/50fps/5000kbps, both with 128k audio. The former will be available as an "hd" mode, while the latter will be available as a new "vhd" mode. It seems slightly wrong to label 540p video as HD, but the BBC maintain that it is roughly as good as existing 1280x720/25fps streams due to the higher frame rate. Because of that higher frame rate, the total bitrate is roughly the same as previous HD video, which is probably the most important metric for get_iplayer. The VF 1280x720 downloads will be quite large (~2GB per hour, double previous HD downloads), so should be classed separately.
