Truffle/APIs and Debugging: Evolutionary steps to integrating debugging and tool support with TruffleVM APIs
- Add a version string to language registration: Language.getShortName() produces a string with both language and version
- Rename SLMain --> SLLanguage (little change current machinery)
- Remove DebugEngine dependence on ExecutionContext: Visualizer access migrated to TruffleLanguage
- ExecutionContext now has only one method left: getCompilerOptions()
- Rename SourceExecutionProvider to DebugSupportProvider, now supplied by implementing abstract TruffleLanguage.getDebugSupport()
- Revise DebugEngine and its helper classes to work with the new APIs
