Faster disk image mounting with FastDMG

I've been using this little tool for years and finally decided to spruce it up and make a proper release: FastDMG. The source is on GitHub.

It's deeply unclear to me how an afternoon or two of coding and testing can produce a solution in every way superior to Apple's DiskImageMounter. Their software is really going to the dogs these days. But to be fair, their disk image mounting tool sucked from day one.
