- add a UserEvent action that allows a manager client to "broadcast" an event

  to all connected manager clients
- update the UserEvent application to use the application argument parsing
  macros and to allow headers to be specified as pipe delimeted arguments
  (issue #5324, original patch by outtolunc, committed patch by Corydon)
