WebFrontend: Decrease the video resolution to 720x405 while keeping the bitrate at 800Kbps. This brings it roughly into line with the recommendations for low-end Wifi streaming of HLS. 800 will be too highly for a mobile/celluar network, so I'll add an alternate mobile profile when I figure out exactly how to detect the difference.
HLS: Bump audio only bitrate to 64Kbps. This is the recommended (apple et al) rate and some would say bare minimum tolerable.
