Add support for logging to a logfile

[GoogleCodeExporter]

R.E.Sonneveld@sonnection.nl:
"it would be nice if gross would log to the $BASE/log directory. E.g.
when having /usr/local/gross, log to /usr/local/gross/log/grossd.log."

I gave it a low priority for now as we already have syslog logging.

I solved it by running gross with the -d switch, and starting it with a script 
that
redirects all output to a file. A cronjob runs to rotate the logfile at 
midnight by
catting all the contents to a timestamped file, and emptying the current 
logfile.

A cleaner log mechanism would still be appreciated though.

Half way through. I have now implemented a new logging mechanism for logging 
queries. 

Format:
a=block d=558 w=5 c=130.232.202.134 s=eino@utu.fi r=eino@utu.fi h=smtp.utu.fi
m=zen.spamhaus.org+3 m=blocker+2

where
a = action
d = delay
w = total weight
c = client ip
s = sender
r = recipient
h = helo/ehlo
m = match from
