Viacom URL Services add media

Added audio codec to all recently revamped Viacom URL services so mp4
videos will not transcode in Automatic on the Roku client.
Schweizer Fernsehen: switch to HTS streaming
Fallback - Set container, video codec and audio codec for files with extension '.mp4'.
Vine - New URL Service.
Use 'movietrailer' as base subdomain (no longer need to check for PlexConnect client this way).
