If you're OK with these changes then i'd be happy to see them merged. This pull supersedes https://github.com/dsimcha/dstats/pull/4

Once merged, it'd be great if you could tag a new release so I can point the code.dlang.org listing to here. I'm not sure how that will go, but I've already tagged v1.0.1 on my repo, so I can see things going more smoothly if you tagged something higher than that, v1.0.2 perhaps.
