Node version 6 required

[antstanley]

More a head's up, but the CLI fails if you're using node v4.6 with error below... upgrading to node v6.9.1 solved this for me..

Error below on v4.6

`/home/ubuntu/workspace/node_modules/svelte-cli/bin.js:607
const { sourceMap } = options;

I had exactly the same problem on macOS and solved it by upgrade of the node.js as well. I used this instruction: https://solarianprogrammer.com/2016/04/29/how-to-upgrade-nodejs-mac-os-x/. On node v. 7.2.0 it works fine, but v. 4.6. throws errors as @antstanley reported. This tool should print more friendly error for the user. I see that there's a PR for that now.

Also package.json does not say anything about required Node.js version, although it should. Or maybe it should be compiled to ES5 / CJS during build.

An engines entry is needed for this.

I notice the engines entry in package.json has been updated. Will close this now.
