Elements overwritten in selector for generic type

[Matthias Schoettle]

When selecting a generic type, classes with the same name (from extended aspects) overwrite others, also happens for primitive types. The result is that only the last added one is shown, which can be from the extended aspect.

There are two problems:

• Filter out primitive types from extended aspects
• Add the aspect name of extended aspects in front of those classes (this avoids overwriting the key in the map of the selector)

[Matthias Schoettle]

Resolved issue #136: Filtering out primitive types from other aspects. Added label provider to display aspect name in front of classes of extended aspects.
