fix a couple of loose ends: sdl_mixer is informed of that OGG is provided by Tremor with its own macro, there is no more a segfault on Tremor cleanup, added new event type and timestamp entry for SDL, removed spurious characters from the japanese translation, uSound errors now are output with SDLTry, uSound doesn't need sound preloading any more
