Project configuration fixes & improvements

- Allow config to specify object "target_path" and "base_path" explicitly, rather than relying on relative path from the "target_dir" and "base_dir". Useful for more complex directory layouts.
- Fix watch_patterns in project config not using default.
- Fix "Rebuild on changes" not defaulting to true.
- Keep watching project config updates even when "Rebuild on changes" is false.
- Disable some configuration options when loaded from project config file.
