Errata for Cougaar 9.4

The following infos/problems/workarounds were detected/posted after Cougaar 9.4.0 was released.

Minor Patch releases:

cougaar-9401 Is cougaar 9.4.0 with new versions of core.jar, csmart.jar, and quo.jar. It contains only patches for the following bugs:
- Bug 1596: Allow Agents created from CSMART recipes to run
  OrgAssets created using the AgentInsertionRecipe were missing the ClusterPG and ItemIdentificationPG, resulting in runtime Exceptions. To ensure that your Agent Insertion recipes work, be sure to open them in the Configuration Builder, and "toggle" the value of your Agent name - change it to something else, then change it back, and re-save your recipe.
  Also note (bug 1594): An exported AgentInsertionRecipe created from a relese pre-9.4 will show errors when you first load it from the database, but these can be ignored.
```
11:48:17,870 ERROR [AgentInsertionRecipe] - Unknown property: Include Item Identification PG=true in component AGG-Agent
11:48:17,877 ERROR [AgentInsertionRecipe] - Unknown property: Include Org Asset=true in component AGG-Agent
```
  As above, just be sure to edit your recipe in the ConfigurationBuilder and re-save it.
- Bug 1590: Extensive Name Server processing load
  Diagnosis: Excessive fetching of (topology entity) attributes to implement Syscond topology polling. The algorithm is changed to be O(N^2). Still not scalable, but blows up less rapidly.
- Bug 1607: Blackboard timstamp service
  The Timestamp service was erroneously reporting "unknown" for all timestamps. This is now fixed.

The org.cougaar.core.persist.NonPersistable interface has been removed. This interface existed (in various packages) since an early implementation of persistence (over four years ago). It managed to survive through succeeding development despite that fact that it did nothing. Because it was attracting the attention of developers and being used (and failing to do what was expected), we decided to to remove it. This uncovered additional, non-functioning, uses. Use the org.cougaar.core.persist.NotPersistable interface to mark classes whose instances should not be saved in persistence snapshots.
CSMART Agent Insertion recipes exported from any release prior to 9.4 will give errors on importing into a 9.4 CSMART. These errors will be something like:
```
11:48:17,870 ERROR [AgentInsertionRecipe] - Unknown property: Include Item Identification PG=true in component AGG-Agent
11:48:17,877 ERROR [AgentInsertionRecipe] - Unknown property: Include OrgAsset=true in component AGG-Agent
```
Agent Insertion recipes in 9.4 must include an OrgAsset. So after importing your recipe, edit it, and fill out the newly required fields: ItemIdentification, TypeIdentification, etc, if you have not already done so. See bug 1594 and the discussion of bug 1596 above..

cougaar bug 3675: CircularQueue.toArray incorrectly copies elements, causing occasional NPE in topology code on startup. See bug for fix or ask for a patch release.
