NAS Key West added

I have added the Naval Air Station Key West trunked system to the Southernmost Feed. Several times while visiting Key West I have seen the Naval fire department running a call and wondering where they were going. Now this adds the missing piece to the puzzle.

The NAS police and other talkgroups are carried on the system, so if they get too chatty I might disable them and keep the fire channel. We shall see about that.
