Kracoeus-7002

Merged from mrudulpolus/KRACOEUS-7002.  Not fully functional.  Known issues are described in KRACOEUS-7745.  
I was ambivalent on this as well, but I ran out of ideas.  The problem I found Is that the Performance Site section and the Other organizations section are almost identical in functionality.  They both populate into a ProposalSite object via a quickfinder and they populate into the same collection.  The only difference in them is what their BO's the quickfinder is looking up and returning.  I've tried numerous things with minimal success. Maybe there's a simple trick I'm missing?
