/** @file newgrf_text.cpp
* Implementation of Action 04 "universal holder" structure and functions.
* This file implements a linked-lists of strings,
* holding everything that the newgrf action 04 will send over to OpenTTD.
* One of the biggest problems is that Dynamic lang Array uses ISO codes
* as way to identifying current user lang, while newgrf uses bit shift codes
* not related to ISO. So equivalence functionnality had to be set.
