Updated lettre (and other crates) and workflow.

General: - Updated several dependancies Lettre: - Updateded lettere and the workflow - Changed encoding to base64 - Convert unix newlines to dos newlines for e-mails. - Created custom e-mail boundary (auto generated could cause errors) Tested the e-mails sent using several clients (Linux, Windows, MacOS, Web). Run msglint (https://tools.ietf.org/tools/msglint/) on the generated e-mails until all errors were gone. Lettre has changed quite some stuff compared between alpha.1 and alpha.2, i haven't noticed any issues sending e-mails during my tests.
