Message:

orxonox::RenderQueueListener: Implemented a rudimentary RenderQueueListener to enable the use of stencil buffer for elaborate alpha blending shaders without creating artifacts from overlapping faces. Also added a XML Port to assign a Model to a certain RenderQueueGroup. Needs to be improved to allow the use of strings for choosing the group instead of a static int which may change in the feature.
