The system for worlds with no rules has been overhauled. Now there are global rules and default rules in addition to world rules. If a world has no rules, it will display default rules if such exist. On any world, global rules will be displayed if such exist.

Also fixed the lack of tab completion for the subcommand section (append, set, insert, etc).

Also changed the old global * designation to _global_. Yea, it's more of a PITA to type, but the world tab complete will now put _global_ and _default_ at the top of the list to make it simple.
