Subject: [PATCH] Override the default latex class name with a new one

* lisp/ox-latex.el (latex): Add :latex-class-name to :options-alist.
(org-latex-default-latex-class-name): The default name of LaTeX class file.
(org-latex-template): Replace default latex class name with :latex-class-name.

Override  the default latex class name in template. It will be very
useful if you are using a class and it's setting is very similar to
one which has been defined in the `org-latex-classes, for example:

If you want to use latex class: "ctexart"  and you find that it's
setting will be very similar to "article", you don't need to add a
new list to `org-latex-classes, just type:

#+LATEX_CLASS: article
#+LATEX_CLASS_NAME: ctexart
