Ok, here's an update of the state of IRRE support in ExtBase. The example is again with CD, Track
and Recording.

An IRRE setup with Track in the middle will be mapped by ExtBase correctly as two 1:n relations
between CD/Track and Recording/Track. As long - this is the catch - you do *NOT* set the
"foreign_label" property. For some reason ExtBase then thinks you want a n:n relation between
CD/Recording. This is IHMO a bug.

So heads up. Use the standard label and everything should work.
