Add the name, comment and lights from N1MM's entry window

Three more things off the screenshot of N1MM's entry window.

A Name box and a Comment box beside the exchange. Neither is part of the
exchange, so an empty one does not hold up a contact and ESM does not wait for
it; both fill the log columns of those names, and a contest that exchanges a
name keeps what was exchanged. Tab now walks the callsign, the exchange, the
name and the comment before coming round again, which is what the boxes being
there implies. The name is filled from the call history file, and what that file
says in its UserText column is written under the entry boxes, where N1MM writes
it.

Two lights beside the run switch: green while a radio is answering, red while
something is going out on the air. The transmit light follows the keyer, so with
cwdaemon it goes out when the message has actually finished rather than when the
text was handed over.

The window is wider to fit the two new boxes.
