asd
use proper REFERER and HOST headers
typo
also fake JS document.referrer
add db field
honor url query params when redirecting to pizza.de
re-implement popup hiding code

Obviously, aptly named function "check4DeliveryArea" also checks for
opening times. Leaving this on would make it much more confusing for
normal users to pre-order. Thus, the popups are disabled everywhere
except when submitting the basket. This should allow pizza.de to
properly set the delivery_area_id and other values, like minimal
order amount.
fix typo
add pry for more convenient debugging
fix encoding issue
