Complete implementation of timestamp event classes

- Add language strings for all timestamp events and demo protocol in VSDefaultPrefs
- Register new timestamp events and protocol in VSRegisteredEvents:
  - VSLamportTimestampEvent
  - VSVectorTimestampEvent
  - VSTimestampMonitorEvent
  - VSTimestampTriggeredEvent
  - VSTimestampDemoProtocol
- Integrate VSVectorClockMonitor into VSInternalProcess:
  - Add vectorClockMonitor field
  - Override increaseVectorTime() and updateVectorTime() to trigger monitor
  - Clear monitor events on reset
  - Add getVectorClockMonitor() accessor
- Add serialization support to VSTimestampTriggeredEvent for persistence
- Fix VSTimestampDemoProtocol to use process's vector clock monitor
- All 132 unit tests pass
