Why deleteHomePageCache() within wpfc_clear_post_cache_by_id?

the post may appear on the homepage so the homepage cache is cleared.
and you cannot avoid it unfortunately.

I added a class to be able to do that with na_wpfc_clear_post_cache_by_id($post_id). Actually just copied yours and made some changes. (yet kept author page, cats, tags, …)
Also limited the deletion of subdirectories to those with integer or page as name.
I think it might be worth adding a similar feature.
