WorldCommand display is not authoritative

[MikkelPaulson]

Display for WorldCommand should output a command that can be run to unambiguously reproduce the interpreted effect.

> Foo, an inn, an inn

# Foo, an inn
*inn*

> Foo, an inn

There are several possible interpretations of this command. Did you mean:

* `create `Foo`, an inn`
* `load Foo, an inn`

The provided syntax for load works, but create doesn't work and has embedded backticks to boot.

Unfortunately, not all fields are currently independently describable, so this is not possible without extending the creation syntax significantly.
