Fixed in gitlab

Both Native (VM and YYC) and HTML5 now connect to the NodeJS server supplied in the bug with a few corrections

1. in the app.js in the 'message' function in a connection the msg is always an ArrayBuffer so needs to be handled accordingly
2. HTML5 only allows async connections so you need to use the new functions network_connect_async() and network_connect_raw_async(), they take the same parameters but are asynchronous so they return the id of the socket which can be used in the async network event to detect a connection complete message and the type is network_type_non_blocking_connect

once those changes have been made then everything works as it should

The problems were caused by

1. NodeJS server is sending a string over ws our code was expecting a Blob of data - if the server always sends Blob;s then everything works as expected
2. VM and YYC were failing as the server was refusing the connection complaining about a missing Host: entry in the header, I have added this header in and now the NodeJS is accepting the connection.

The changes to support the new NodeJS version have resulted in a couple of new functions as well as a number of fixes/changes to this functionality, so it's not a simply thing we can drop in to 2.2.4 at the moment. Accordingly, I have set this as 2.3.0 for now.
