Helper scripts to fix some buggy users.

We have a lot of forged users that have bad fullnames due to
historical versions of our fullname computations; this function will
clean those up.

Also, we have a bunch of users with emails like foo|mit.edu@mit.edu
that were the result of a mirroring bug that we want to get rid of
from autocomplete -- putting them in a useless realm name will do.
