s2Member v160503

• (s2Member/s2Member Pro) Security Enhancement: This release forces CURLOPT_SSL_VERIFYPEER to a value of TRUE in the AWeber SDK that is used when/if you integrate with AWeber. In short, this forces AWeber to have a valid/verifiable SSL certificate before any data is exchanged between s2Member and the AWeber API behind-the-scenes. Props at WordPress security team for reporting this.
