Add LethalConfig with suitable custom options

The custom callback attempts to prevent modifications mid-round. Use
IsHost to check for permissions, as IsClient is always true for
everyone even in local single-player setting.

There is a bug in LethalConfig which makes it possible to modify entries
bypassing the callback once per round, but it is pretty hard to abuse:
