significant work on Zinc logging...

- add ZnObjectLogLogger to record ZnLogEvents in Object log
  - add ability to log errors for additional filter granularity
    in log.
- install error event in the several(!) in Zinc client/server code
  where exceptions are silently ignored - exceptions logged as
  debug event along with hundreds of other non-exception based
  events)
- use error event in ZnSingleThreadedServer>>logServerError:
  which also swallows errors ... returns an error response
- Zinc tests refactored to:
  1. turn on logging Transscript or ObjectLog depending upon
     whether tests are being run interactively or not
  2. trace test running in object log to make it possible to
     correlate client/server log errors with the test being run.
