WooCommerce Dynamic Pricing 3.2.7

* Fix: Fix issue when using multiple rules, with role selection and selecting a label from one rule set selected the role from another. #23
* Fix: Fix issue where the dates for advanced category rules were not respected in the shop page.
* Fix: Fix issue with Composite Products support where prices in the cart were displayed as 0.
* Update: Cache product discounts from the store so it does not have to be re-calculated every single time.

* Update: Added a custom integration for WooCommerce Memberships to allow membership discounts to be applied before Dynamic Pricing discounts.
The default is that Memberships will apply discounts on top of anything Dynamic Pricing has already done. This update allows you to change this by
using the following filter. To use this add it to your functions file, or elsewhere you have custom code.

add_filter('wc_dynamic_pricing_apply_membership_discounts_first', '__return_true');
