[ORYX] Hack to Fix getChildById

oryx.getChildById.fix.js

ORYX.Core.UIObject.prototype.getChildById = function(id, deep) {
	var i, child, ret;
	for(var i = 0; i < this.children.length && ret === undefined; i++){
		child = this.children[i];
		if(child.getId() === id)
			ret = child;
		else if(deep){
			ret = child.getChildById(id, deep);
		}
	}
	return ret;
};
