I use Node-red version 1.2.6 with johnny-five 1.5.0 and the normal settings.js entry

```auto
jfive:require("johnny-five"),
j5board:require("johnny-five").Board({port:"COM5", repl:false})

```

After upgrading to johnny-five version 2.0.0 I get the following error at starting Node-Red:

```auto
Error loading settings file: C:\Users\Public\Documents\HA1.node-red\settings.js
TypeError: Class constructor Board cannot be invoked without 'new'

```

How to correct?
