Added methods for preparing and sending mail

Jason,

Let us know if there's anything here that you don't agree with.  We added to methods to Remedy.php.  `callPrepareMail` returns an array that is all the information you need to be able to send a mail that is attached to a call.  If passed an override, `callPrepareMail` will also send the mail through the function `callSendMail`.
