Heiwaboke Crisis

Thanks to alouette for finding some more sound bugs, I've gone through and replaced more instances of problem sound files. In my defence, I never identified this problem on my computer since I have Japanese IME installed, but obviously lots of other people have had problems. My apologies! If there are any more bugs out there I'm grateful to anyone who can point them out.

Lesson learnt: next game, use testers o_O
