Windows cannot spawn process w/o shell

[rdig]

Description

Windows cannot execute commands without spawning a new shell. At the moment we are skipping the shell and spawning a new process directly.

Steps to Reproduce

1. Install via npm i es6g-init or clone repo

Expected behavior: To install the package

Actual behavior: Error: spawn ENOENT

Environment

• OS: Windows 7 x64 Professional
• Node: 6.9.1
• Package version: 0.1.0
• Dependencies versions: not applicable

Proposal

We can either revert back to using the exec() method or pass the { shell: true} option to current execFile() method.

I think the second option seems a better approach.
