Made the UDP message to change the free text message optionally send ASAP

This  message now  has  the ability  to simply  change  the free  text
message or to change the message and send it ASAP.

The message_aggregator reference UDP server application exercises this
feature by sending a new free  text message on any edit and requesting
it be sent  by WSJT-X when editing is finished  i,e, RETURN pressed or
focus moved away.
