smbspool drop-in replacement

I have put Patriot's drop-in replacement for 'smbspool' into Woof.

I already announced Patriot's initiative here:
http://bkhome.org/archive/blog2/201007/samba-printing-smbspool-replacement.html

The change in Woof is that we now have /usr/lib/cups/backend/smb which is a script -- in previous puppies it was a symlink to the 'smbspool' executable.

I have also updated the Samba printing HOWTO page:
/usr/share/doc/samba-printing.htm
