- Added short description for control files

 - Ensured that BLZ and KTO consist only of digits, even if the
   user has specified something different.  Banks won't accept files
   otherwise.

 - Applied fix for a y2k issue that prevents some banks from
   accepting the files.

 - Improved README file, added links to the web page and the mailing list.

 - Added TODO file

 - This shall become version 0.4
