"none" header avoids result post-process
This patch introduces a new header argument which hide all code block
results from Emacs so that they are not processed into Emacs-lisp
objects; a process which may take a great deal of time for large
objects.
* lisp/ob.el (org-babel-common-header-args-w-values): Adding the new
"none" header argument.
(org-babel-execute-src-block): Don't do *any* result processing if the
"none" header argument has been specified.
(org-babel-sha1-hash): Remove the none header argument from
header arg lists when calculating cache sums.
(org-babel-insert-result): Flesh out some documentation.
