[Suggestion] Add config to prohibit breaking return beacons and scooping up dimensional plasma

[LTCatt]

I'd like to see the plasma pools and beacons used as fixed teleportation points for my players, rather than being able to move them around.
But there's no configuration available that allows me to disable them from destroying or moving :(

The first thing could probably be fixed with a loottable changing the beacon's drops to nothing, but the second would need a config I think
