[PATCH] Run latex more than once for LaTeX src block evaluation

Hello,

I have a small patch for `org-preview-latex-process-alist' making
the default setting for LaTeX source block evaluation be running
latex three times (instead of the current one). It is sometimes
necessary to run latex more than once to produce the final
document, a phenomenom described in the docstring for
`org-latex-pdf-process' which itself runs latex three times by
default. This patch just brings the former variable into parity
with the latter.

Subject: [PATCH] lisp/org.el (org-preview-latex-process-alist): Run latex
 multiple times

* lisp/org.el (org-preview-latex-process-alist): Run latex three
times by default

It is sometimes necessary to run latex more than once against a
given .tex file; something ably explained in the docstring for
`org-latex-pdf-process', which exports LaTeX by running latex
three times (by default). This patch brings
`org-preview-latex-process-alist' into parity with that variable,
running latex three times by default when previewing LaTeX.
