Title: Goodbye to CompositeTruthValue

Remove CompostiveTruthValue. Remove VersionHandle.

This code was not generic, added a lot of complexity, was hard to debug and verify. There are easier, better, faster ways of dealing with ContextLink's that are more generic and less invasive.

Remaining work item: simplify atom merge.
