fix longstanding issues with console EOL handling

Historically there has been an issue with line endings in console.pl
which meant that the spot line (for instance) had to be 1 character
less than the window width (e.g. 79 chars in an 80 char window).

This has now FINALLY been fixed.

In the process I have fixed the issues of extra things like
cq/itu/us state/dxgrid strings overwriting or coming out in a
stupid priority. So the priority is now from nearest/smallest
area -> largest wiz: QRA, US State, ITU or CQ zone. So you
can have them all on, but ITU zone will always trump CQ zone.
