As reported [on Meta](https://meta.discourse.org/t/discourse-subscriptions/140818/352?u=justin), moderators could access all of the subscriptions data (plugins/prices/subscribers) and manage them. This should not be the case, so this PR adds a route constraint to 404 moderators from these routes.
Feature requested here: https://meta.discourse.org/t/subscriptions-allow-users-to-purchase-one-time-products-multiple-times/173732/
There may be cases where a site admin wants to allow the repurchasing of a product. This implements the functionality by adding a repurchaseable toggle in the admin screen when creating a product. This saves an attribute to the Stripe product metadata.
When a user has already purchased an item with this toggle enabled, they will be able to purchase it again when browsing to `/s`.
Adds full support to create coupon/promo codes in the Admin > Plugins > Subscriptions section of the plugin. The Create Coupon button opens a form on the same page, and the active checkboxes toggle the active status of the coupon code.
This adds support for Stripe Promo Codes in the user checkout process.
Also adds a discounted field to User > Billing > Subscriptions to show the amount or percent discounted.
This does not currently add in support for creating promo codes in the Subscriptions interface (that will come at a later point in time). Instead a coupon can be created with a promo code right from the Stripe dashboard.
