Subject: don't let emailauth user's email address be changed on preferences page
X-Git-Tag: 3.20150610~72^2~1

don't let emailauth user's email address be changed on preferences page

There's no real problem if they do change it, except they may get confused
and expect to be able to log in with the changed email and get the same
user account.
