CB Paid Subscriptions

Currently both CBSubs Emails and Mailer is calling comprofilerMail directly instead of going through cbNotification. This causes the email footer to be missing. Change this to use cbNotification as it doesn't appear necessary to be calling comprofilerMail directly since sendUserEmailFromEmail function can be used to specify custom from name and address.
