Add: News post for 16.0-beta1 release

[2TallTyler]

Let's get 16.0-beta1 out soon.

I welcome opinions on what should be shared in the overview, it's a big changelog and not everything fits. 🙂

Long socials post

OpenTTD 16.0-beta1 is out for testing! Features include:
* New options for trains to drive backwards instead of flipping
* Setting for open multiplayer companies where anyone can join
* More features and bugfixes!

To Do

• Write socials text
• Create news image
• Before publishing: change URL of linked Backwards Driving post (Add: Explainer post about backwards trains feature #394) to reflect the date when that is actually published
• Before publishing: add link to TT-Forums title game competition post

Overall looks good. A few minor changes suggested.

For the socials, not too keen on the "Trains can go backwards" line... They've always been to turn around to go backwards ;)

Perhaps:
"Trains can go backwards" --> "New options for trans to reverse or drive backwards"?
[NB. This does work in the changelog, where there is a linkout to more information]

And for the multiplayer setting:
"Multiplayer companies can be set to allow anyone to join" --> "Setting for open multiplayer companies where anyone can join"?
[Nice to have this phrased differently in the socials and changelog, gives two bites at the cherry for helping people understand]
