Fix: ':recursive' and org-publish-attachment

The following patch fixes a bug in org-publish. There must be a better 
way to fix this (maybe it is fixed already) cause this one only works on 
the local host (?), but my poor lisp...


It is possible to supply the ':recursive' property to a project in 
org-publish-project-alist to publish recursively.

But org-publish-attachment crashes if one of the target sub directories 
does not exist. Here is a fix.

I just was about getting my feet wet with elisp. But fortunately I 
found, that a 'recursive' property is already provided in 
org-publish.el! Could not find it in the docs. I feel it realy should be 
documented, since it is an great feature. My orgfiles already have names 
like emacs-orgmode.org, emacs-gnus.org and emacs-whatever.org :-D

But this did not work with static files if the target directory did not 
exist.




This is what I tried to do:

(setq org-publish-project-alist
       '(("org-notes"
          :base-directory "~/notes/"
          :recursive t
          :base-extension "org"
          :publishing-directory "~/htdocs/org-notes/"
          :publishing-function org-publish-org-to-html
          )
         ("org-notes-static"
          :base-directory "~/notes/"
          :recursive t
          :base-extension "css\\|js\\|png\\|jpg\\|gif"
          :publishing-directory "~/htdocs/org-notes/"
          :publishing-function org-publish-attachment)
         ("public-notes" :components ("org-notes" "org-notes-static"))))

M-x org-publish-project RET public-notes RET


The images live in a subdirectory 'img/'.

When I deleted the sub directory 'img/' under ':publishing-directory' 
the publishing of the images failed.




Have fun,
