Email to friend works!

Took me all morning, but the shellfie sends via e-mail as an attachment.

marcosmailer3.php: Attaches shellfie to e-mail and sends it without body
copy. Just the shellfie.

marcosmailer4.php: I'm starting to work on sending a multi-type e-mail
so it allows text in the body, and a base64 image as an attachment.
