Enabled the use of Debugger-specific watch/locals models.
- Modified WatchModel to handle storage of an hierarchy
of WatchItems.
- Factored out code for asynchronous population to
AsyncWatchModel and added a mixin for convenient
handling
- Added base class for synchronous models.
- Implement simple, synchronous models for CDB, greatly
simplifying code and finally getting manual
expansion right.
