Reward Points Module for ZC v13x

[hem]

Just in case I caused confusion, ideally I would like to credit:

10 points for every pound if sub-total less than £25
20 points for every pound if sub-total is £25 or more

All points redeemed worth 0.01 pound.

(Idea being customers enticed to spend above £25 to gain double points per pound.)

You would need to change the process function in includes/modules/order_total/ot_reward_points.php
