* Add recovery code support for two-factor auth

When users enable two-factor auth, the app now generates ten
single-use recovery codes. Users are encouraged to print the codes
and store them in a safe place.

The two-factor prompt during login now accepts both OTP codes and
recovery codes.

The two-factor settings UI allows users to regenerated lost
recovery codes. Users who have set up two-factor auth prior to
this feature being added can use it to generate recovery codes
for the first time.

Fix username styling regression introduced in #1063

When transmitting data in a HTML-encoded element like <content type="html" />,
relying on newlines being preserved is not wise, since HTML by itself
does not care for newlines - it cares for <p> and <br>
