What's in this update
Feature and Operational Changes Reworked Timeout routines.
When a Timeout occurs, Timeout Message is sent to proper Port.
When Timeout is cleared, controller sends Courtesy Tone to inform users repeater is "back".
Properly mute audio when Ports are linked and controller needs to speak.
This means that even if a linked Port is active when you enter a command, that Port will be muted so as to properly hear any controller speech in response to that command.
Changed Tail Messages to call Command Macros instead of Message Macros.
This allows for much more flexible messages.
All Ports are automatically unlinked during RCP operations. 2 seconds after RCP operations cease, the previous Port linking status is restored.
