BackgroundMusic/build_and_install.sh
Kyle Neideck d95b0d8b1a
Add a repackage option (-r) to package.sh.
It takes an expanded Background Music .pkg installer and repackages it
into a new .pkg installer. It's mainly useful for code signing, since
you have to expand the unsigned package, sign each of the bundles,
repackage it and then sign the new package.

Also, fix build_and_install.sh putting the BGMXPCHelper dSYMs in the
wrong archive.
