Incompatible change in the Java Module

Hi all,
the place where the composite looks for the Java model elements are
defined is going to change from the nature to the layer. The new folder
is Looks/Composites/org-openide-src/ on the layer.

This move allows even project unaware modules to add new looks to the
composites.

If your module adds looks into the srcmodel composite looks you have to
move them into the folder Looks/Composites/org-openide-src/ on the
layer.

I am going to commit this change on the next Monday.

Tomas
