Sends email asynchronously.
The email is sent using the locally installed mail client. But this function does not wait for the result.
Some email clients seem not to like more than one attachment.

With outlook you can keep text empty and attach a html file. Than Outlook will use the html file as content of the email and allows you to send html email.

Falls back to WinSendMail.SendAnsi if Unicode support is missing in older Windows versions.

Outlook loves to return failed, if you pass in email address for To/BCC/CC and no name.
