Reward Points Module for ZC v13x

[hem]

This script will delete all empty multiples on the config menu just copy and paste it to SQL patch. However if you use a table prefix you will need to set `configuration_group_id` to `YOUR_PREFIX_configuration_group_id`

#NEXT_X_ROWS_AS_ONE_COMMAND:2
DELETE FROM `configuration_group` WHERE NOT IN (
SELECT `configuration_group_id` FROM `configuration` WHERE 1); 

Apropos to this, I've submitted a bug report regarding this (http://www.zen-cart.com/forum/showthread.php?t=123631). If you copy the attached file to admin/ then this script will run fine.
