* Fully convert to the pkginstall framework by using it to manage
directories required at install time.
* Rewrite the canna rc.d script to ensure that all needed directories
are present before the daemon is started.
* Miscellaneous touch ups to the DESCR and MESSAGE files.

into ${LOCALBASE} and use symlinks and file copies to put the files
into the ${IMDICTDIR}.
