Option to chose directory for latex preview images

* org.el (org-latex-preview-ltxpng-directory): New option.
  (org-preview-latex-fragment): Store LaTeX preview images in
  `org-latex-preview-ltxpng-directory'.

Added an option `org-latex-preview-ltxpng-directory' with a path
where the preview images will be stored.  The default does not
change (small little ltxpng scattered all over the place) but now
the user can chose an absolute path and put all the images on a
single place.
