Create standard Node.js app for alerting to HTML5 apps

[adamfowleruk]

I've previously built a situational awareness app that provided a HTTP and WebSockets server for provisioning HTML apps to web browsers. It also provided a HTTP restful server for MarkLogic alerts to fire messages to. These were immediately sent to the clients.

Would be great to almost productise this piece. As a later extension, provide a Node.js proxy for the REST API in HTML5 apps using MLJS. I can provide original code on asking.

I've started this in DEV branch. Created classes to manage Node.js web server with websockets support for alerting.

TODO:-

• AUTH mimicking
• REST /v1/ URL proxying
• Add easy alerting support to MLJS Core (test what's there already)
• Support multiple clients and test
• Test for XSS and cross-session vulnerabilities

Going to leave security for a later version - too complex to implement quickly. May need refactoring of auth code generally in MLJS. Also leaving testing of vulns for later.
