Use `nil` for the `options` parameter to unregister the function associated with the given identifier.
Use `nil` for the `get_formspec` field to denote that the function does not have its own screen.
Use `nil` for the `privs` field to denote that no special privileges are required to use the function.
If the identifier is already registered to another function, it will be replaced by the new one.
The `on_select` function must not call `worldedit.show_page`
