Directed messages sent to high level portals
A dispatcher or Routine line sending a message to a portal will now first attempt to match a message entry with the same name as the sending dispatcher/change object. If this fails, then the default entry (_!message)
is looked for. If this also fails, then the platform looks for a Portal called _!message and forwards the message to it.
Within this portal, specific entries may extract the message.
1. Many message types to be directed at a portal and then
individually handled within via separate entries.
2. Message handling to be encapsulated in a hidden portal (must be called
_!message) rather than having to have message entries/flows right
at the top portal, which may be visible to end users.
