Subject: [PATCH] Add a new startup keyword to preview LaTeX fragments

* doc/org.texi (Previewing @LaTeX{} fragments): Document the startup
  keywords which can be used to preview or not LaTeX fragments.
(Summary of in-buffer settings): Improve formatting and add an entry
for the variable `org-startup-with-latex-preview'.

* org.el (org-mode, org-startup-options,
  org-startup-with-inline-images): Add the variable
  `org-startup-with-latex-preview' which can be used to preview LaTeX
  fragments on startup. This variable is set to `nil' by default.
