Simpler iPhone language pack deletion script

My earlier script is a pain. It works fine but I'm not happy with it because it's too much work keeping up with iPhone developers and their screwy names for the language packs.

For some reason, fr.lproj and French.lproj weren't good enough, so there's some fr_FR.lproj popping up, and not only for French, but a variety of languages. The ISO language code for Spanish is "es," so the language pack should be either "Spanish" or "es," but now I'm seeing "sp", "sp_es" and "es_ES." "Sp" isn't an recognized code for any language.

For a script that essentially greps a list of 60 languages in the old format, I don't want to have to add another 30 to deal with these new names popping up. It's easy to add them to the list, but without rewriting the script, it means the user has to be asked "yes or no" for even more languages.

I never thought it would become a project I had to maintain anyway. I will rewrite it so that it's flexible and can handle new languages on it's own, and to lessen the number of times the user has to say yes to each language, but here is a simpler script to use for the time being.

Since most people want to remove everything except English and Japanese anyway, this simple script will do that. It only asks one question "Do you want to delete everything except English and Japanese?" and if you say yes, it does it. It won't have any problem with new language codes because it gets a list of all languages, filters out English and Japanese and deletes everything that is left. Simple. Almost as simple as my very first post on the subject.

Enjoy.
