The rounding mode sum_by_net_keep_gross is supposed to be the
consumer-friendly algorithm. However, some consumer-friendly prices are still
impossible, such as 15.00 incl. 19%. Previously, the system would round
to 15.01, because it's the gross price derived from the closest net
price. With this PR, it rounds to 14.99 instead, because consumers like
paying less more than they like paying more.

Product categories can now be marked as "cross-selling categories", causing them to
appear in the add-on checkout step as additional recommendations, depending on
their cross-selling visibility (always, only if certain products are already in the cart, or
only if they qualify for a discount according to discount rules).

Allows organizers to test their shop as if it were a different date and time.
Implemented using a time_machine_now() function which is used instead of regular now(), which can overlay the real date time with a value from a ContextVar, assigned from a session value in EventMiddleware.
