reaction should add a version subcommand
I know there have only been two releases so far, but as you make additional ones, there is no simple way to determine what version one is currently running.
So, I suggest either:
reaction version
or
reaction --version (and/or -v)
I guess it would be nice to have both. That way, -v (--version) could be added to normal commands as well and the version would be shown along with the regular output:
reaction -v show
