Hi,
I think ox-html should insert a viewport to make it mobile friendly. I
think it's not a W3 standard, though, but it's also just an additional
meta tag. I'd like to hear from somebody who knows about html.
This patch adds this tag by default.

Subject: [PATCH 7/7] ox-html: Use viewport
* ox-html.el (org-html--build-meta-info): Insert viewport.
(org-html-viewport): New custom variable.
* ORG-NEWS: Mention viewport.
* org.texi: Mention org-html-viewport.
Viewport makes org-generated html work well with small screens.

Hi,
I pushed this prematurely in a7becba686e5dcf6424697ac54b4671abeb34f92, so
if somebody feel that this should not be part of ox-html it can still be
reverted.
