Prepare all stuffs for using Facebook JavaScript SDK

• Append "fb-root" element (if not exists)
• Append Facebook JavaScript SDK resource (if not exists)
• on() let you attach callback for "ready", "login" event
• render() will parse XFBML (ex: Like Button) without asynchronous context

Firstly, get your application id on https://developers.facebook.com/, then initialize FBReady with the appId.

var fbready = new FBReady( your_application_id );

You don't need to install "fb-root" or script code to import SDK.

Attach callback for "ready" event. This will be called when anything about connection is done.

fbready.on("ready", function(){
	console.log("Connected to Facebook !");
});

To do something with authenticated context, "login" event is usable.

fbready.on("login", function(){
	console.log("Logged in !");
	FB.api(...);
});

FBReady doesn't have any interface to login. Call FB.login() on your own context.

Use render to show XFBML widget such as "Like Button".

fbready.render();

No need to call it in callback. render() just registers callback and waits for preparing application.

• If FB object exists, FBReady try to use the FB and doesn't install new "all.js".

• If FB.init() has been already called, that looks like working but not good.
  You will see a message like "FB.init has already been called".
  It may be caused by installing code for widgets such as "Like Button"
  because they call automatically FB.init.

• In context of callback for FB.getLoginStatus(), FBReady does not work.

• ready : Connection process is done
• login : Logged in

Register callback for the named event.

Fire the named event.

Render facebook widgets on the page.
This call FB.XFBML.parse()
