Send Test Email Ability.

Users should be able to preview the email before sending to recipients.  This could be accomplished with a "send test email" button on the email compose page.  The formatting in the "email compose" window does not accurately represent the format in the actual email that is sent to recipients, especially when changing font size / colour or adding an image to the email.  The test email would ensure the sender can make final edits to font colour / size, image size before sending to the recipient(s).
