PIFIA was deleted, since it is now part of PICALib. Hostgroups can now have
variables. The "shellcmd" attribute can now be used to give an arbitrary
command to reach any host via firewalls and such. Some minor improvements and
bugfixes were made.
Directory handling fixes were made. The alarms were moved to another package
(PICAlib). A simple manpage was added. Another function was added to user.pm.
