create alias hoodie -> hooded_sweatshirt
After consulting the wiki more closely, I'm thinking we should make the name of this tag less ambiguous to try and stop people from using it on posts which should be tagged hooded jacket instead. Correct me if I'm wrong, but as far as I can tell it should be hooded jacket for the ones that open up at the front and this tag for the ones that don't (which would also make open hoodie entirely redundant).
