- added an option flag "ignore_missing_package_ids" to xo::db::Class ad_instproc instantiate_objects to
omit warnings about missing package_ids for parameters. Currently, OpenACS creates apm_paramter
objects without a package_id. This is not so easy to fix in the kernel, since e.g. the
package_id of acs-kernel is created after the paramters are added. One could use an
"magic object id", but that would need special handling on several places.
