Master branch broken - No traits showing Piece Definer

The last couple of 'cleanup' commits to PieceDefiner have broken it completely, it now loads up with an empty list of traits in the left hand trait list. Commit 7fcf64a seems to have done the damage.

It's the Renderer -> GamePieceRenderer refactor that is the problem, everything else is fine.
