• Add popup preview mode
• Avoid race condition between users: When the popup gets loaded, a coupon gets reserved for a user until he retrieves it, closes the popup or a timeout has elapsed.
• Record popup on open instead of page load

After launch improvements

• Allow settings z-index for popup
• Add shortcode support for popup
• Add loading spinner when fetching coupon
• Allow popup elements to be undefined

Rename from "wp-coupons" to "unique-coupons"
