Added John Reilly's enumports/addprinter/delprinter scripting code plus the

fix for the Win9x printer drivers.
Changed command names to add "command" string on the end for some consistancy
with the other scripting commands.
Added '%P' option to tdbpack/unpack to store long comment string.
Made port name be "Samba Printer Port" if no enum port script given.
Fixed prs_uint32_pre code to cope with null args.
Jeremy.
