Added sendNewRequestNotification to the Notifications helper. This method will send out a notification upon arrival of a new Request to all users who have an active role for the Request's scope and the roles as specified by the getRoleLogicsToNotifyUponNewRequest. Also renamed getRoleLogicsToNotifyUponeNewRequest to getRoleLogicsToNotifyUponNewRequest.
