Blog posts understood by jekyll
Update the publish mechanism

I use the M-x publish/publish-post! which currently loads
a temporary org file and add the needed jekyll metadata.
Then exports the html which such metadata.
Thus letting jekyll posts the output correctly formatted.

Need to abstract away my configuration and make a mode of this.

Why not see to enrich the existing org-jekyll.

What I like with this is that I do not touch any of my org files
(No strange yaml embedded in org html quoting block... which modifies
the org file)
