CHANGE-484 - Quantities added to cart should adjust to stock rather than just a message
CHANGE-18 This is code for the new installer for version v1.6

It is still not complete. Lots of help text still to add and some tweaking and security hardening left to do.
Also note. We have left the old installer code in the zc_install_old directory temporarily.
