Don't require node 6 to run react-server-cli

Thanks @lidawang! Will be nice to pick up lerna/lerna#192 when it lands so we can drop the extra two copies of cli.js here. 😛

This seems like its going backwards to me. Node 4 supports destructuring, but its behind a flag; can you try adding the --harmony_destructuring flag to https://github.com/redfin/react-server/blob/master/packages/react-server-cli/bin/react-server-cli#L1, rather than removing the destructuring? I don't think we want to try to support node < 4.

@doug-wade - This is actually just the top-most entry point for react-server-cli. We have a couple of extra copies laying around until the next version of Lerna lands, but after that it will just be this one tiny file that needs this treatment. :)

(Note the require("babel-core/register"); at the top)

@gigabo oh, I see. sorry @lidawang, lgtm 👍
