Some gadget messages

 Done I think you could have done this yourself? Have you tried? (I could be mistaken)

Thanks (also for the other messages). I'm not sure if I could have done it. I know that /en messages can't be edited (which is probably good so that no one adds nonsense to them), but I'm not sure what about those without any suffix, i.e. the English messages related only to Translatewiki, but imagined it to be better to ask first.
