=ID Property update=

ID Properties weren't being duplicated (by shift-D or any of the other
duplication functions).  So now ID properties are duplicated in the 
main copy_libblock function, which (as far as I can check) covers all
ID-contained ID properties.

I also updated the constraint system to copy pyconstraint ID properties
on shift-D.

This would probably be a good thing to add to the stable branch, btw.
