Log Message:
Updated to version 3.0.3.

Merged the two rules in netbsd_lists.cf into one because problem reports
mostly do not contain "x-send-pr" anymore.

Disabled installation of netbsd_lists.cf in PKGSYSCONFDIR (it is still
included in the "examples" directory).

Changes since 3.0.2
===================

 - Fixed possible memory bloat from large AutoWhitelist db files

 - Fixed where user defined rules scores became ignored

 - Updated parsing code for several Received: header formats

 - Increased some BAYES_* scores for the network+bayes score set

 - Document set_tag for Plugin API and added get_tag

 - Additional bug fixes.
