Remove version command

[erikquinn]

The version command is using prop.version, which is no longer maintained, so when it attempts to log the version number, it instead says:

The only place the version number is stored now is in package.json, which ends up in layout.hbs and loadingView.hbs. Somehow we should get this command printing the correct version number.

I give zero 💩s about the command myself.
