Updated the way of relating reference authors to PIs. This is now done with the many-to-one association ReferencesAuthors => PrincipalInvestigator.
Now showing "Is PI?" and "Is collaborator?" form fields for each author.
Now guessing PI from author name.
Also nicer layout of references form.
Fixed association with GrantInvestigator => PrincipalInvestigator.
