* Important - Removed old Update Helper dependencies. If you are running a WooCommerce version older than 3.1, you will not see any prompts to update Conditional Shipping and Payments from now on, and will need to install extension updates manually!
* Fix - Incorrect 'Membership Plan' condition behavior when user is not logged in.
* Tweak - Added 'woocommerce_csp_order_total_contents_only' and 'woocommerce_csp_order_total_condition_incl_contents_tax' filters to modify the behavior of the 'Order Total' condition.
