Fedora 27 Release Announcement

[Ryan Lerch]

I have made a bit of a start on the release announcment post on the
magazine.

It still needs a lot of work and fine-tuning, and lots of the content is
just pastad from the beta announcment, but it is a start.

I have also drafted up the Upgrading to Fedora 27 article.

Images for both posts are also done and on the posts now.

cheers,
