This patch fixes the generation of references for
one-to-many associations.
Currently, refAddLink( .. ) throws an MDFNotImpl
exception if the second association end is not multiple.
The patch changes this to allow refAddLink() to be used
for one-to-many, many-to-one and many-to-many.
It works well for us. I think a better fix should
consider the one-to-one case as well...
