add attribute for who invited user to group

Hi,

Would it be possible to extend the content of the Invitation Services
"Registration Page" to accept (and store) the set of attributes
associated with the InCommon Research and Scholarship attribute bundle ?
It would also be helpful if in the name of the invitor (sponsor) were
saved (this would allow us to send a "renewal" email at some future
date, asking if we need to keep this external person in our local Registry).

I believe this is mostly a question of fields on the form that is
presented to the invited user, and the DB schema where this information
is stored.

I'd suggest that the R&S attribute bundle represents a "reasonable" set
of info to collect and store about a person.
