Add more blocks to physics control

WORLDGUARD-3884 - Reported by CoolDev457

Hello,

In the physics config : physics: no-physics-gravel: true no-physics-sand: true

It would be nice, with the new blocks of 1.11, to add no-physics-concrete-powder: true And maybe at the same time no-physics-anvil.

Best regards,
