Big 'ole update to implement multi-db aware packages. Don't try this yet,I can't *possibly* have gotten all the right files added and removed inone fell swoop!
bootstrapper can now load either the Oracle or PostgreSQL acs-kerneldatamodel. It checks on-the-fly for which db is configured in the OpenNSDdatabase pools allocated to OpenACS. Only acs-kernel is correctly self-configured at this point.
