Validation for Decorator Command Sets

[dselman]

Adds syntactic and semantic validation for decorator command sets (DCS).

Changes

• Adds the option validate to DecoratorManager.decorateModels to validate that the DCS conforms to the model
• Adds the option validateCommands to DecoratorManager.decorateModels to validate that the types, namespaces, declaration and properties referenced by the commands in the DCS exist in the model being decorated
• Adds the option addMetamodel to BaseModelManager to add the Concerto metamodel to the model manager when it is constructed. This is useful for decorator command sets because they reference types from the metamodel.
• Updates the vocabularyManager.generateDecoratorCommands to generate valid commands and to use versioned namespaces. Test has been updated to validate the input to DecoratorManager.decorateModels
