Rework of the early access achievement — Wilford Steam update #346631

When I started making the game I wanted to incentivize players to try it. One of the ways I decided to do that was to create an achievement rewarding people who played during early access. I hadn't thought it through though. As I see it, it's really important that people are able to 100% a game. Closing off an achievement to every single person who gets the game after release is a sure way to annoy a lot of people. And we can't have that of course ːsmileː
