This is a bit pedantic, it's unlikely that the executable would be
called `-v` or `--version`. However, it seems slightly more correct to
disregard argv[0] when checking flags.

Added a new dependency to take care of pulling in the version from git
at build time.
Args handling is minimalistic, but there wasn't any before, so I figured
this might do for now. (Eventually, some proper `--help` and usage
output might come in handy?)
