  - FEATURE: audio streaming - adds capability to stream to multiple remote broadcast
    servers (Broadcastify, Icecast v2.3 and v2.4+, and Shoutcast V1 and V2).  Each
    stream can be independently configured with a delay.  Audio calls are directed
    to one or more streams by attaching one or more stream identifiers to each alias.
- - Requires Java 8 (or newer) for compatibility and eventual changeover to JavaFX
  - Extensive GUI updates for tuner, channel and alias management.  Includes new
    'Now Playing' channel view and 'Detail' view.
  - Updated alias list management of alias id values and wildcards.  Weighting is now
