Get all active coupons for item

[bsteen]

The script only gets the active coupon that was first uploaded for an item because it just pulling the coupons from https://www.hfqpdb.com/browse. However, items can have multiple active coupons. To see all the active coupons for the item, you have to go the item page. By only looking at the coupons on https://www.hfqpdb.com/browse, false positive are generated if that coupon there does not match the HF coupon, but the HF coupon was already uploaded and is listed as an active coupon on the item page.

Fix this by going through all the items on https://www.hfqpdb.com/browse, "clicking" the item, and pulling all the active coupons from the item page.
