Add support for headers in native mailer

The native mailer is able to have additional headers, but it wasn't possible to give it any headers in the configuration. Swift mailer may have a content_type key but not native mailer. A new "headers" key is now allowed in the handler configuration, so a list of headers may be given to the handler. Only native mailer supports it. Related to #272
