Comment 1 for bug 1104517

The commit here contains a single commit which addresses the OU setting check, as well as IDL fixes for bug 1104516. I plan to split the changes out and will create a working branch in the usual place for signoff. For now, just getting this bug documented and the preliminary fix out there: http://git.evergreen-ils.org/?p=evergreen/tadl.git;a=commit;h=de88b461de89ca541b5f18b9f048bdeaecbff60f
