Language IDs

Currently, the scheme is to use international phone codes as language IDs, unless they're out of range. When creating a new translation for OpenTTD pick a number vaguely related in some way. Or something else.

Valid language IDs are listed in the table below. The cases, genders and the type of plural form is only given as reference. Authorative are the definitions in OpenTTD's language file for each language.
