ox-latex: Tiny fix to latex-matrices pseudo-elements

* lisp/ox-latex.el (org-latex--wrap-latex-matrices): Make sure
  contiguous element is also an Org table.
ox-latex: Possibly make a matrix out of tabular environment

* lisp/ox-latex.el (org-latex--math-table): Properly create matrix if
  "tabular" environment is used.  Make sure cells are centered instead
  of applying usual alignment rules.
org.texi: Remove extraneous backslash in key sequence

* doc/org.texi (ASCII bar plots): Remove the backslash character in
the key binding sequence for orgtbl-ascii-plot command.

I think that this backslash is not needed, since previously in the
same section, at subheading "Graphical plots using Gnuplot", there is
a similar key sequence without backslash @kbd{C-c " g}.
