<p>Reorder and enable/disable crumbs rules.</p>

<p>If a newly installed module introduces new crumbs rules, these rules will find themselves in the "inherit" section at first. Priority and enabled/disabled status of rules in the "inherit" section is inherited from matching wildcard rules in the "enabled" or "disabled" section. The '*' wildcard rule counts a enabled, if it is in the inherit section itself.</p>
