Reward Points Module for ZC v13x

[hem]

Ken- that's as it should be. I've passed a 0 value to the reward_points_display. I'm going to talk to the author of the Google Checkout mod and see if we can't remove it from the actual checkout, but for now at least it is not coming up as a chargeable item.

Here's a quick hack of the googlecheckout.php which adds the reward_points_display module to Google Checkouts list of Order Total mods to ignore. Unfortunately is list is hard coded rather than databased hence the code change.

Just extract the php file to includes/modules/payment/
