Ross Burton's versioning

Ross, please don't do that. Rewrites are not bad in themselves, but please let the version number reflect that. Minor version number updates like the one you did should be reserved for minor code updates; not for major rewrites.

Not that I care in this specific instance; I don't even know what Devil's Pie is supposed to do, let alone why it would be useful; but as a rewrite-from-scratch usually introduces new bugs, it's not fairly useful to have just a minor version bump.
