[arch-general] Initial AIF localization support (patch)

For the past few days I have been working on adding support for localization in AIF. I think I have marked every string that contains text that can be translated, but it is possible that i have missed some. Also there is some work to be done in the makefile, as I couln't figure out how to make for loops in it. Also the code to the language selection screen sint working, yet. I will try to get that to work. I hope some one familiar whit the AIFs codebase would check this out and corret if something is wrong. If this isint turned down as waste of ?something? or something else, I will translate this into Finnish, also Im alredy translating the offical installation guide to finnish 1/3 redy I think. :D
