[Click] Newbie problem with configuration file.

[Vaibhave Agarwal]

hi wang,
though i havent used ip-router myself, but if you read the 
make-ip-conf.pl, you can clearly make out that,
if you are using user level click, then
you should use:
"toh::Print(toh)->Discard"

instead of 'toh :: ToHost', which is meant only for kernel click.
