Highlights for version 0.2.1

v0.2.1 - 10/20/01
- Engine updates
   - Global namespace - all storage object names must be unique throughout
      the whole system, not just within a particular layer.
   - Internal locking (instead of a lock file) to prevent multiple writers.
   - Improvements in the Task interface.
   - Engine can now be built with Electric Fence for memory debugging.
   - Plugin collision-resolution - If two plugins with identical IDs are
      loaded, the engine keeps the one with the higher version number. Before,
      it just aborted.
