Timeline service protocol support with Observatory UI

Timeline service protocol support with Observatory UI

Service Protocol:
- _clearVMTimeline (clear timeline)
- _getVMTimeline (fetch timeline)
- _setVMTimelineFlag (control recording)
- _getVMTimelineFlag (...)
- _getVMTimeline service unit test

Observatory:
- timeline page with record on/off, clear timeline, and refresh buttons.
- trace-viewer based timeline view that runs in an iframe driven by a small javascript program

Misc:
- Fix default enable logic bugs
- Add 'Debugger Pause' timeline event
- Threads can have a name and that name will be displayed in Observatory
- Tighten up locking when printing JSON
