* imgages in body-attach with title / alt attribute get them removed while adding fancy attributes * Added fancybox to image inlined in posts. Un-hooked the old lightbox from frio and vier and excahnged that with fancybox hooks. * Excluded images in "type-link" divs from being "fancied" as they have no images but pages linked to.
