Option for sending both html & text in the one email.

[Richard Uren]

Hi Daniel,
Great component. FWIW : Quick change to allow sending both html and text in the one email & thought i'd feed it back. Update Below.
Cheers
Richard

// HtmlBody
if ($this->sendAs === 'html' || $this->sendAs === 'both') {
$message['HtmlBody'] = $this->htmlMessage;
}
