/**
* Template tag for breadcrumbs.
*
* @todo [JRF => Yoast/whomever] We could probably get rid of the 'breadcrumbs-enable' option key
* as the file is now only loaded when the template tag is encountered anyway.
* Only issue with that would be the removal of the bbPress crumb from within wpseo_frontend_init()
* in wpseo.php which is also based on this setting.
* Whether or not to show the bctitle field within meta boxes is also based on this setting, but
* showing these when someone hasn't implemented the template tag shouldn't really give cause for concern.
* Other than that, leaving the setting is an easy way to enable/disable the bc without having to
* edit the template files again, but having to manually enable when you've added the template tag
* in your theme is kind of double, so I'm undecided about what to do.
* I guess I'm leaning towards removing the option key.
*
