use wins server to browse smb printers outside of the local network

I won't be able to test this, as I can't create such a setup (not enough computers/routers etc.)

I have two quirks with the patch. Of course, better have it this way than not at all, but still:

a) isn't /etc/samba/smb.conf distribution dependent?
b) according to smb.conf(5) manpage, parameter name and value are not case sensitive (thus, looking for 'wins server' in the file matches only one in 2^10 possibilities -- of course, we're very lucky and most distributors will just use lowercase).

Anyways, I'm nitpicking. Thanks for the contribution and if I get a confirmation that the patch applied as given in the current code works, I will add it depending on release schedules.

Thanks

use wins server to browse smb printers outside of the local network  (bis)

here is an update of my previous patch based on Cristian Tibirna remarks:
1) /etc/samba/smb.conf is "standard" amongst mainstream distributions I know
such as Debian, Redhat Fedora, Suse, if anyone can give a significative
counter-example here, of course would I do the required adaptation
2) smb.conf parsing improved by a more attentiv re-read of man smb.conf ;)

note: this patch was diffed against KDE 3.5 svn sources (the previous used
3.4.2 sources from Fedora) 

hope this can help.

SVN commit 469327 by tibirna:

use WINS for SMB printer detection. Thanks to Gerard Macinenti for
patch.
