mailsend-go: download ældre versioner

This release fixes Issue #76.
The options -printCerts and -verifyCert now take effect while sending
mail, not just with -info. Added -verbose as a shortcut for
-debug -printCerts -verifyCert together.
No need to update unless you need certificate details or verification
while sending mail.
Please look at ChangeLog for details.
The binaries are cross-compiled with
go-xbuild-go
Do not forget to check checksums of the archives before using.
Thanks.
