 jQuery is not needed on a page until just before the first script that
 depends on it. If scripts dependent on jQuery are registered properly via
 `wp_register_script()` or `wp_enqueue_script()`, then the script
 dependency system is smart enough to know where to load jQuery. Therefore
 jQuery should be registered in the footer by default (allowing the script
 dependency system to do its magic). This simple change can be made in wp-
 includes/script-loader.php in `wp_default_scripts()` and will no doubt
 improve performance on lots of sites. There may be some other default
 scripts that would benefit from this change too.
