feat: Use Quoted-Printable for the text part (#3986)

This is needed to protect from ESPs (such as gmx.at) doing their own Quoted-Printable encoding and
thus breaking messages and signatures. It's unlikely that the reader uses a MUA not supporting
Quoted-Printable encoding. And RFC 2646 "4.6" also recommends it for encrypted messages.
