Add 'viewmyprivateinfo', 'editmyprivateinfo', and 'editmyoptions' rights

These are needed for OAuth grants.

Note that we don't bother with a 'viewmyoptions' right, since the
majority will be determinable from just observing the interface.

Note that the fact of having a confirmed email address cannot be
reliably hidden, and if the user has 'sendemail' they may be able to
determine the real name and email address by sending an email to another
account that they control.
