More consistent naming of “difficulty: playground / explorer / regular”

[TentativeConvert]

Some ideas:

• Game rules: none / lax / regular
• Learning mode: real world (dangerous) / playground / supervised (default)
• Identity: freak / explorer / learner

In any case, it should be made clear what the default setting is.

I love "Game rules: none / lax / regular". Seems very self-explanatory.
