Title: Promotion Usage Count in Admin

Currently there is no way for a admin (non-tech) to know what the current usage count of a promotion is, this makes it impossible for them to know if the promotional will still work for a new customer.

This PR adds a simple 'Current Usage: x' display on the promo admin.
