Fine-grained permissions (build vs interact) and Environment permissions

[Poikilos]

• (done upstream in Bucket_Game) implement fine-grained permissions (build vs interact)
• (done upstream in Bucket_Game) implement environmental permissions (what can happen in the environment and what the environment can do, regardless of player or player presence)
• (moved group-based aspect of issue to Area and Protect and Group System Brainstorming Area #335)

It was for this reason that OldCoder split privileges. In Bucket Game people with the "interact" privilege can open doors, harvest plants and use machines such as furnaces and grinders, they can also access unlocked chests. But they can't dig or place nodes. They need the "build" privilege for that.

This allows the creation of public facilities such as those in Wonderworld. People can use them but they can't damage them.

Excellent. That resolves the wontfix issue at minetest/minetest#7057!

Some stopgap measures:

• default:cloud is fully opaque and unbreakable (confirmation needed)
• https://github.com/minetest-mods/maptools: "Adds various special versions of normal blocks, tools, and other map maintainer tools."

To split the issue, I'll move the group-related ideas to #335
