Adds a subscribeAll() method to the client to handle any events

[AndrewRayCode]

Usage:

client.subscribeAll(function(message) {
    console.log(message.action);
});

Only accepts one handler and will overwrite any previously existing
handlers. Addresses #111

Coverage increased (+2.1%) to 76.056% when pulling 09ba503 on DelvarWorld:subscribe-all into 46cbc22 on glenjamin:master.

Sweet! Do you have any thoughts on the next version release? I'd like to use this in a little side project

[glenjamin]

Will likely cut a release in the morning UK time
