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
