Windows 10 dependencies issue when installing as global

After linking node-windows as described in the readme
```bash
npm link node-windows
```
one should link its dependencies as well
```bash
npm link xml
```
for the installation to succeed
and
```bash
npm link optimist
```
for the service to be started

Start with the README's global linking instructions and reproduce the Windows 10 installation and service-start commands shown in the issue. Trace how the xml and optimist dependencies are resolved, then confirm that the documented global installation works without manual dependency links.
