Bug 518317 - [UMLPropertiesView] Autocompletion for type of properties

- new auto-completion editor:
  - no binding to uml element
  - available in example for property type
- add a predicate filter for INameResolutionHelper   
- add completion proposal and processor for UML NamedElements
- fix a bunch of quality warnings for Java 8
