nodemailer patch

[mrfrase3]

seeming that #27 has been waiting 3 years to be accepted, and I needed nodemailer, here is a patch file for the latest version of master.

You can use this with patch-package

keystone-email+1.1.0.zip (take the .patch file out of the zip)

Thanks, we are also hoping, that this would be merged at one day.
