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.

We didn't include them on many pages, or the ones we did weren't always
useful. Also try to keep the boilerplate to a minimum so you can see the
important bits in the title. 'Arch Linux - ' comes first in all titles, and
from there it can be filled in with something useful.
