* To define labels for a setting named "competition_level" you could
* for example call it like this:
* AddLabels("competition_level", {_0 = "no competition", _1 = "some competition",
* _2 = "a lot of competition"});
* Another example, for a setting with a negative value:
* AddLabels("amount", {__1 = "less than one", _0 = "none", _1 = "more than one"});
*
* @note This is a function provided by OpenTTD, you don't have to
* include it in your Script but should just call it from GetSettings.
