Prestashop Checkout Tweaks

1) On the checkout procedure -------------------------- - 'Your billing address' : please remove this box, I don't need it (Obviously don't need "Use the same address for billing." as well) (Also no need for 'Choose a delivery address:' if there is no addresses) - 'Your shipping address' : it currently lets me checkout without entering a shipping address - please make that section compulsory This also looks bad right now, with the 'update' button badly formatted. Basically if there is no address, and it is a guest order, then there should be an address field. Guest checkout should be possible, without having to enter any login screen.
