BREAKING CHANGE

• PR #408: Update Mail constructor to signify which parameters are required for sending all email
• The Mail() constructor now requires $from, $subject, $to and $content parameters like so: Mail($from, $subject, $to, $content). Those are the minimaly required paramaters to send an email.
• Thanks to Casey Wilson for the PR!
