Visitors

An additional option for the removal/cleanup of
old data records was added. Two initial data query
options were added for post analysis of stored
data. The first tells how many visitors were seen
in the last X days. The other tells the delta
between the first and most recent visits.

Very minor code fixups were done. Minor
configuration bugs were fixed.

There are various minor changes and bugfixes in this
release. The cookie cleanup is now working. Additionally,
long log file lines were only being read from stdin. Some
code cleanups, function documentation and better autoconf
configuration has also been included. The default results
ouput has had a very minor change.

Only minor fixes were made. A problem in which the
program deleted records that were still within a
valid visit/time period during the end of run
cleanup phase was fixed. The location of the
Berkeley DB libraries can now be specified if
necessary.
