Cleanup all Param objects when any rules change

Cleanup all Param objects when any rules change

Fix license date for new junit test.
Updated some comments.
Ensured different control loop names in different rule sets of new junit
test.
Used different mechanism for examining facts in new junit test.
Fixed typo in comment.
Changed the way new junit checks for existence of facts.
Fixed another typo in comment.
Updated clean-up rules in CLC template and added junit test to verify
that Params are cleaned up appropriately.
Removed code that retracts $manager objects so that the manager clean-up
rule will be used, instead, thus ensuring that all associated objects are
deleted when the manager is deleted.  This was done for amsterdam, CLC,
and casablanca templates.
Added an extra fireAllRules() after calls to fireUntilHalt() to enable
clean-up rules to fire in junit tests.
Address Josh's review comments.
Enhance junit test to compare actual object references to ensure that
Param objects are as expected.
