[CoR] FAQ copy from Emma
[CoR] correct login forms for CoR (non)auth

e.g. CoR don't want passwords for users, but we're doing email auth,
so have to be consistent.
Genericise login email subject

as per model of other emails in default templates.
[CoR] override emails
[CoR] whitespace tweaks
[CoR] comment out alerts

(pure expediency: I haven't had time to ensure all texts are
cobranded correctly wrt translations, don't know that part of
the codebase/app very well, and it seems like less of a key
feature, for time being.

Will be easy to switch on when there is time to check the
trnanslations!)
