Rightjs Core → 2.0.0 Release

I think we could win something in size if we use a new closed layout, with local wars, kinda like that

var RightJS = (function(self, doc) {
  var HTML = doc.documentElement, ....;

  // the rest of the code in here
})(window, document);

this way we will have one isolation function instead of several here and there, plus we can shortify things with local vars and so one. And this should be extremely useful when it will come to the safe-mode development.
