D6417: Avoid duplicates in virtual overrides code completion proposals

[Friedrich W. H. Kossebau]

kossebau created this revision.
Restricted Application added a subscriber: kdevelop-devel.

REVISION SUMMARY
  Currently methods which have multiple overrides in the inheritance
  chain are also displayed as often. Filtering these duplicates out
  based on the signature improves the situation as a first step.

TEST PLAN
  E.g. QWidget subclasses have lots of methods repeated, with this
  patch no longer.
  Extended unit test yet to be written, patch to be updated soon.
