patch-af is new to adjust configure in order to find the tcl/tk config
files.
Also adjust patch-aa which didn't completely reflect the previous upgrade
to scotty-2.1.6 (version numbers off-by-one.)
and patch it up a bit. Yes indeed, phk is back in the tcl+snmp arena.
Update to 2.1.5, add the ability to probe several communities with
the IP-discover function.
