* fix(notification): incorrect date header format
The date header in the email envelopes was incorrectly formatted missing a space between the `Date:` header and the value of this header. This also refactors the notification templates system allowing people to manually override the envelope itself.

Allow users to configure the TOTP Algorithm and Digits. This should be used with caution as many TOTP applications do not support it. Some will also fail to notify the user that there is an issue. i.e. if the algorithm in the QR code is sha512, they continue to generate one time passwords with sha1. In addition this drastically refactors TOTP in general to be more user friendly by not forcing them to register a new device if the administrator changes the period (or algorithm).
Fixes#1226.
