Let the server owner, or the users themselves, decide if they get achievements based on active time

I'm hosting a server for myself a couple of other mates, and some of us like playing more, mostly focused around experimenting with spaceship designs, reworking factories etc. We ran in to an issue where one of our mates wasn't getting achievements, and we eventually discovered that the server only gives achievements to people who've been online for at least 50% of the server time. This is causing issues, as sometimes we leave the server running to get long timeframe research, or resources to be collected etc.

It would be really nice if, either on the server config(With a warning to people who connect), or as part of each Users config themselves, we could control whether this "Achievements only granted to active players" functions or not. I'd love to turn that off so that we can run the server as much as we want, without then having to do silly things like getting someone to afk for 8 hours straight to bring their "active time" back in line to get achievements again.
