[Dx4win] DX4WIN.CTY Release #56 - second call

[Jim Reisert AD1C]

I've updated the release notes for DX4WIN.CTY Release #56:

   http://www.country-files.com/dx4win/download/#56

I am trying to make some changes to the database to be more compatible
with the contest country (CTY) files.  This required changing the
default CQ and ITU zones for United States and Asiatic Russia.  I
updated the prefix mappings so that you should not notice any logbook
differences (I've checked against my 80,000+ QSO log going back to
1974).  I am still looking at China (BY), Canada (VE) and Australia
(VK).

I'm also trying to define better start and end dates for callsigns, so
that they are "retired" from the contest country file automatically.
This is a work in progress, as you can tell from the release notes.  I
don't expect that anyone's DX4WIN entities will change if I'm careful
and do it correctly.  There are ways to tell if I messed up (see the
main DX4WIN country file web page).  This is a very time-consuming
activity, as you may imagine.

Please let me know of any other additions or corrections.  The release
is scheduled for the weekend of December 6-7, thought it could be
sometime during the week before (but after December 1).

Thanks & 73 - Jim AD1C
