Purchase without Account BS

The new modular architecture introduced since Oscommerce Ver. 2.3.4 can be seen to some extent, allows add-ons that are much easier to install than in previous Osc versions.
Compared to the previous PWA versions, which required extensive changes to dozens of files, this version, thanks to the (still incomplete) modularity of Osc, manages without functional compromises with changes to two files (+ associated language files).
The add-on allows shop visitors to shop without a customer account.
