- Replace WITH_APACHE2 by USE_APACHE, rename httpd.conf.xxx to
httpd-xxx.conf and fix configuration if APACHE_VERSION > 20.
- Don't use the MCAL back-end by default for Kronolith, it is
deprecated.
- Deinstall bug reported by John Nielsen <john (at) jnielsen.net>:
respect LHORDEDIR.
- Fix horde-passwd installation / deinstallation.
- Don't bump PORTREVISION, because running installations are not
concerned.
