Cache the rules in a global variable in each script, as JSON, and use JsonUtils directly to evaluate them. This will allow us to close the WpConf in the future after loading the scripts. Also change the order of the return values of the match_rules_apply_properties function to be able to easily ignore the number of changed values, which is useless in most cases.
