  Clarify some documentation of queues.conf.sample
  
  It had always been possible to explicitly specify a "blank"
  value for a sound file in queues.conf and have no sound played
  back. The problem with this is that it would result in some ugly
  CLI warnings from file.c.
  
  This commit introduces a check when playing a file in app_queue
  to see if the name of the file is zero-length and return early if
  that is the case. Also, the ability to specify the blank sound
  files in queues.conf is now mentioned more clearly in queues.conf.sample
  
  (closes issue #14227)
