Clarifying that only legal versions of the ruleset can be converted to Environment rules. As it stands there’s scope to illegally scrawl “the player named Machiavelli wins all games”, or worse, in the ruleset wiki and have it become a live rule of Giolitti, if I endorse it as an Environment without noticing. The altered version would never legally be in the ruleset, but the Environment doesn’t currently care about that, it’s just a “convert wiki page revision into valid rule text” machine.

Also adopting the strict “revision” terminology of the wiki, for clarity, although I think “edit” has been fine so far under common usage.
