[Building Sakai] updating links to other tools when copying Lessons from site to site

[Bruce Cota]

I'm working on a project that uses archive/restore heavily.   We had to 
hack around this issue with for samigo and assignments in lessonbuilder 
(by modifying both tools and lessonbuilder).  I think we had a similar 
issue with announcements and assignments.   It would be nice if there 
was a standard api in the archive/merge code for updating entity 
references, as there is in site copy.

However there are some limitations. The way it works depends upon whether the copy mechanism uses updateEntityReferences. "Duplicate site" and some other things do. But importing an archive file does not.

What I do is leave behind a fixup pointing to the core assessment. As soon as the user publishes the assessment, Lessons will notice it and fix up the reference to point to the newly published assessment.
