add redirects for existing news

the url redirect option does not play well on github. So instead we
keep the new url pattern for news and add redirect files for the
existing news links.
That way old news are accessible from the old and the new link, ex.:

old: /project/2018/07/16/release-1.0.8.html
new: /news/2018-07-16-release-1.0.8

New news do not need this redirect.
