Title: i18n: make emails in lms translatable

The translatable strings of email texts in lms/templates/emails are not extracted by ```rake i18n:generate``` because the ```conf/locale/babel_mako.cfg``` does not include them.
And several emails in lms are not translatable because they do not use ugettext.
