Yarn's fix for Mantis 3017 (Certain HUD elements don't work after the changes to strings.tbl). Not very happy with the way it fixes thing (it only solves problems for French, German and Polish, which kinda makes the changes to strings.tbl in r9761 somewhat pointless) but it makes sense to wait for SDL and truetype support and then fix everything properly then.
