[Xen-Soluce] Recurring Subscription 2.0.0 Fix 1

I have a somewhat complicated user upgrade system and originally purchased the Upgrade Coupons addon. I had some difficulty in implementing that addon for my needs and XenSoluce was very prompt in providing a solution to this. I also needed to extend the operation of the coupons and XenSoluce quickly provided this companion addon - Recurring Subscription - to make that work for me. I really can't say enough good things about both the addons and the support they provided to make this work for complicated conditions.
