    js: load games using FileReader.readAsArrayBuffer()
    
    Using .readAsText() meant that trying to load a non-text file (for
    instance something that's not a save file at all) would generate an
    "RuntimeError: index out of bounds".  This would then leave the
    Emscripten runtime in a broken state.
    
    It might even be possible for a real save file not to be valid UTF-8,
    for instance if it came from a platform that used a different character
    encoding for random seeds.
    
    There's still a problem with opening very large files, apparently
    because Emscripten tries to stuff the entire file onto the C stack.
    That will probably have to be fixed by properly exposing the incremental
    file-loading API to JavaScript.
