fix double quoted-printable encoding in forgotten password email.
Double encoding was introduced by 50c7a0cc1791.
Discussed on MoinMoinBugs/ResetPasswordEmailImproperlyEncoded.

The problem was caused by a bug in python 2.4.3 and above, which doesn't
QP-encode the message as previous versions do it.
