[rt-users] changing $Organization

[Christoph Badura]

Our setting of $Organization has included a blank because the version of
RT I installed originally didn't yet complain about blanks in $Organization.

We're getting tired :-) of the related warnings on upgrades and I'm trying
to fix the references in the database this week.
I've found and fixed references in the Links and Transactions tables.

Is any other table to be fixed? Is there maybe a canonical list of tables
and columns to fix?
