    Fix malformed libspotify at build time (GitHub issue #136)

    libspotify 12 is distributed in a malformed manner,
    in that its Info.plist contains an incorrect
    CFBundleExecutable value, preventing submission
    to the Mac App Store. This commit adds a build script
    to CocoaLibSpotify that corrects this at build time.
