Added support for Wildcat 3.x: 


At least Herald is able to read FILEAREA.DAT to locate the areas and 
ALLFILES.DAT to get the file descriptions. He does not support that 
weired passwording scheme and multiple paths for one area. Because WC
does not use security levels to grant access to areas this value is
also void.

Herald ignores the passwords in WC's config, the date of last access
as well as upload dates and file size are not used - Herald takes both
from the file itself.

And, Herald is up to now not able to write ALLFILES.DAT. WC uses a btree
system to store all information, at first I have to figure out how it
works.

But at least you can create file lists and announcements for WC 3.x systems
and generate FILES.BBS for d'bridge mailers. Autoadded files will not be
inserted in ALLFILES.DAT but show in the lists and FILES.BBS, files removed
will vanish from both lists and FILES.BBS.
