- For reasons of consistency, and to avoid that "generated-src" directory is deleted by IDE dev tools' EcoreBuilder, start specification of directory for generated edit code with a '/' (just like the model, editor, and test code directories)

- Add prefix "generated-" for directories of generated edit and editor code (not used in default AF3 distribution)

- Adjust all annotations that inherited from IDerivedAnnotation to use the new DerivedAnnotationBase class
- EOperation cleanup
- Move getValue() from org.fortiss.tooling.base.utils.AnnotationUtils to org.fortiss.tooling.base.model.base.impl.DerivedAnnotationBaseStaticImpl

Extends the Derived annotation, such that element-specfic values can be returned; Useful for aggregate annotations.

 - Change return type of getValue() to T
 - This allows for more type safe implementation of the underlying calculations
 - The former abstract base class DerivedAnnotationBase used Object as a return type for getValue() to due an EMF code generation bug for generics if the base class is located in a different .ecore file than the concrete class. For interfaces, this bug is not triggered.
  
refs 1841

Introduce "derived" annotation, i.e. based on calculations instead of explicit annotations / model contents can be implemented

- DerivedAnnotationBase meta-model element, with getValue() EOperation, and a extensive documentation.
- Corresponding DerivedAnnotationValueProviderBase, implementing a read-only, text-view of the calculation result
- To implement the above, move handling of annotation EClass & factory to ValueProviderBase
