Anti-Afk / anti spawn kill

[Yassine]

Idling is absolutely fine. We have proper systems in place to make sure that it won't affect your stats.

I think that Yassine uploaded a pull request for adding spawn protection, but I haven't been able to get to that yet. I agree that we should add something like that.
