Payment module TPV 4b (Banco Santander) adapted to osCmax 2.5

[celeroncillo]

Hi, I adapt this module to add a Payment module TPV 4B based in Zhen iT payment Module for oscommerce, but change little code lines and correct files to work in oscmax.
This module is more usual in Spain and easy to install / uninstall, is automatic modify MysQL files.
I test it in my OSCMax ecommerce, and work perfect!, less sales comission than paypal and others.
