- removed all redundant classes AbstractDecoratedComplexCellWithTextStyledTextActionHandlerDatabindingEditingSupport, AbstractComplexCellWithTextStyledTextActionHandlerDatabindingEditingSupport, AbstractComplexCellDatabindingEditingSupport
- changed DataStateValueEditing Support so that complex cells are still supported

- When inserting copies of objects as a result of a copy&paste operation, the inserted model elements is shifted by an offset. This gives visual feedback to the user that the paste operation has actually been performed.
- Notes:
 + Some model types are not handled yet (see ticket)
 + Although maybe an obvious approach, this feature cannot be implemented as a method in HierarchicElementCompositorBase:
   o It is not the base class of all affected compositors
   o HierarchicElementCompositorBase resides in org.fortiss.tooling.base, where as the required methods for detailing with layout information are in org.fortiss.tooling.base.ui

- Ensure that in each session, the hint how to create new connections is displayed until the user has managed to create three of them.
- (Side note): The current implementation cannot distinguish connections created interactively by the user, and connections created by a model-transformations. However, we can assume that a user who is able to issue a model-transformation also knows how to create a channel in the GUI.

- Ignore update of IDs that may be triggered massively when saving a model that contains a lot of generated artifacts for which IDs are typically not assigned.
- Disabling the delivery of notifications during the assignment of IDs is not possible since the kernel needs to be notified about ID changes.

- Prefer the potentially a bit less efficient but safer Display.getDefault.syncExec() over Display.getDefault.asyncExec() to avoid NPEs triggered by model modifications
refs 2323

- Ensure that UI updates triggered from EMF notification mechanism are executed in the UI context (using Display.getDefault.asyncExec())

 - In case the label could not be found, return a string representation of the value. This is useful to implement custom label providers for model elements are edited in combo boxes.
 - Prevent potential NPE

- Add IAnnotationValueProvider.isHidden() that allows to hide annotations from any view (useful for internal attributes that should not be exposed to the user). Default = false
- Extend AnnotationEntry and AnnotationFilter accordingly

- GSNPositionedEditPartBase*: Avoid code duplication by pushing refreshDecorationFigure() to PositionedEditPartBase
- PositionedEditPartBase.refreshDecorationFigure()
  - Avoid SWT Image leak by reusing the same icons
  - Add more null-checks to implementation
- MarkerViewPart -> column updater: Avoid SWT Image leak by disposing old image before setting a new one

- Keep order of elements to be selected (e.g., EENum values) etc. by using a LinkedHashMap instead of a TreeMap

Adds the possibility to filter the list of available choices for an enum-type annotation via the annotation's value provider.
Therefore, a map containing the class of the to be filtered model elements and the allowed enum literal must be given in the constructor of the value provider.

Bugfix: Use annotation instance key in setValue(). This is already done in getValue() / getLabel()

- Add Id, version, and ConQAT tags to XML files

* Mainly documentation cleanup
* Remove some commented out code
