Breaking changes

• Depending on your configuration, your certificates actually get checked. Which can cause an aborted connection if the certificate can not be validated.
• Messages don't get flagged as read unless you are using your own custom config.
• All Header::class attribute keys are now in a snake_format and no longer minus-separated.
• Message::getTextBody() no longer returns false if no text body is present. null is returned instead.
