Pass video posters through info.

* ennum.el (ennum-post): Add video-posters slot.
(ennum--read-post): Set video-posters slot when creating post object.
(ennum-publish-post, ennum--feed-entry): Pass video-posters in info
communication channel.
* ennum-html.el (ennum-html-link): Handle video links differently from
normal org links since they require access to the info communication
channel. Get poster from info instead of reading the source tree
directly.
(ennum-export-video): Delete function.
(org-link-parameters): Unregister ennum-export-video.
