Format all news items using markdown

Implements FS#13741. A preview function is also added so working with news
items is easier to make sure you get the formatting right.

This will result in some older news items looking a bit weird if they didn't
put linebreaks in all the right places, we can fix a few of these as we
notice them.

+    <p>News articles are formatted using
+    <a href="http://daringfireball.net/projects/markdown/syntax">Markdown syntax</a>.
+    Please use this syntax if at all possible over raw HTML, which can be used
+    if Markdown doesn't support what you would like to do. Before posting, you
+    are highly encouraged to use the <strong>Preview</strong> button to check
+    your work.  Javascript must be enabled to use it, but it will render the
+    news item exactly as it will appear on the news view page.</p>
