[ipv6calc] New version 0.48 is available

Hi,

since my improvements I got no information about troubles, therefore I published now the final 0.48 version.

Major changes:

Update databases

General: - replace md5 function from openssl with a copy of coreutils (licence issue) - add support for IEEE/iab.txt database ipv6calc: - add support for recognizing 6to4 addresses generated by Microsoft OS ipv6logconv: - add support for recognizing 6to4 addresses generated by Microsoft OS - add support for ISATAP addresses

Hope this helps, Peter
