cowdb0.11.3

Release cowdb0.11.3 has had the PHandle clear method refactored. A small change, but it will make a huge difference to COODBMS. PRolons will now be aware of when a well known name is removed, when a reference from the links table is removed and when a reference from a child or parent rolon is removed, and can take appropriate actions.

The removal of a reference from a child Rolon or from the links table will initially be noops. But when we add namespaces (and later, inferencing) these will become significant events. As it is, COODBMS need only address the removal of a reference from a parent CSec or from the well known table--and gracefully delete itself when appropriate.

Things should proceed a bit smoother now.
