I also saw the potential for sitemap pinging to use hooks. Therefore, I converted the ping_sitemap_xml function to use hooks (systems/sitemap_ping). Hooks take a run function which has a $url passed into it. They should return a string result (or null for no results).

Currently, there are no sitemap_ping hooks.
