Massive rewrite to speed up the database writes.
Using a single database now with duplicate keys
where the keys are the IP numbers. Added a purge
command and removed the garbage command. Fixed
some leaking memory bugs and properly closed the
database in a few places were it was not
properly closed. Updated the docs to reflect
this and bumped both the database version and
release number. Running on a FreeBSD 3.x machine
and a Solaris 9 machine.
