some progress, some bugs

Made some small progress on Semantic Relations today. View now has a Semantics feature, There is now a class called SemanticRelationCSecRolon and another called SemanticRelationDuRolon. And the DescriptorUnits drawer now has a SemanticRelationDescriptorUnitDescriptorUnit. Not a lot of code, just a bit of a mess to get my head around.

Then there was the copy bug I found this morning. That took a while to track down. Then tonight I ran into what I suspect is an applicability bug on crPage. I'll fix that in the AM and then release both bug fixes, as well as the other code.
