Infinite loop on clash creation when constructor method is omitted

Currently, class definition should have a constructor method to work correctly..

(function(){
    XM.define("com.Circle", {
        centerX: 0,
        centerY: 0,
        constructor: function(x, y) {
            this.centerX= x;
            this.centerY= y;
        }
    });
})();

However, if constructor method is omitted, the framework will keep creating a class.

This is because constructor method provided in class definition will override the generic constructor method on native object. Therefore, if omitted the framework will execute the generic constructor method which contain the reference to the class itself, hence triggering the framework to further execute the generic constructor method. Thus, lead to the infinite loop.

Failure of "this" reference inside a listener method

If a class were attached by a listener via addEventListener or attachEvent, a this reference on the listener function will return an undefined instead of reference to the class itself (The undefined result is a valid javascript behaviour, but not an expected result in this framework).

sample:

(function(){
    XM.define("com.Circle", {
        centerX: 0,
        centerY: 0,
        constructor: function(x, y) {
            this.centerX= x;
            this.centerY= y;
        },
        initialize: function() {
            this.addEventListener("mousedown", this.onMouseDown, false);
        },
        onMouseDown: function(e) {
            console.log(this); //return undefined instead of Circle
        },
    });
})();

Ability to do byte accuracy loading (a.k.a: XHR2)

Currently the ScriptLoading only able to do XHR load (i.e: only event of "start loading" and "loading finished" that tracked). In the future, might add capability for XHR2 loading (i.e: able to get the value of actual byte loaded). This will give better accuracy on preloader percentage value
