add contextmenu "PlantUML Parser" in the Find-result-view

[k3b]

As a Java-Developer i want to see a graphical display of all classes that implement a java interface.

Example usecase:

• In the IDE i right-click on the interfacename and select "Find Usages"
• In the Find-Result-Window I select "Usage in extends/implements clause.
• It would be greate if i could call the contextmenu "PlantUML Parser" from any tree node in Find-Results-View that only consists of those classes in the Find-Result

Currently the contextmenu "PlantUML Parser" is only available in the Project-Structure-Tree-View
