ES5 and DOM4 shim for all browsers with IE6 and IE7 support

based on:

Status: Stable Beta Demo Try it in IE7 (or in IE6 ¬_¬)! And take a look at the source

Goal

Normalizing the JS and DOM across all browsers
Less code (eg less closures, reusable functions) & file size
IE6+ support
Include all we need from ES5, ES6 and DOM shim in one file
some extra stuff (if you don't need it, use a.noextras.js instead of a.js)

Caution !!!

This lib is not about performance in IE < 9
The a.ielt8.htc requests should respond with the mime type "text/x-component"
That's all cautions

Install

###(Note: if you don't need EXSTRAs use a.noexstras.js instead of a.js)

For modern browsers: Add main script in head section
```
     <script src="a.js"></script>
 	
```
For IE8 support:

First[!] add a.ie8.js in head section

   <!--[if IE 8]>
   <script src="a.ie8.js"></script>
   <![endif]-->

Add a.js in head section
```
   <script src="a.js"></script>
```

For IE6 and IE7, and IE8 support:

Add a.ie8.js and a.ielt8.js, a.js in head section

   <!--[if lt IE 8]>
   <script src="a.ielt8.js"></script>
   <![endif]-->
   <!--[if IE 8]>
   <script src="a.ie8.js"></script>
   <![endif]-->
   <script src="a.js"></script>

Put a.ielt8.htc to the root of your site

EXSTRAs

IF INCLUDE_EXTRAS == false -> broken Object.defineProperty will be deleted

INCLUDE_EXTRAS:

Exporting these objects to global (window)
1. browser
2. Utils.Dom.DOMStringCollection
3. XHR from https://github.com/Raynos/xhr with customisations
4. (If where is no any other) $(selector, root) alias for root.querySelector(selector) (with ">[any selector]" support)
5. $$(selector, root) alias for root.querySelectorAll(selector) (with ">[any selector]" support)
6. $$0 alias for $
Extending objects
1. Object.append(object, donor, [donor2, ...])
2. Object.extend(object, donor, [donor2, ...]) (Object.append with overwrite exists properties)
3. Object.inherit(Child, Parent)
4. Array.prototype.unique()
5. String.random(length)
Extra polyfills
1. 'reversed' for <ol> with DOM API
2. HTML*Element.labels

Same-domain limitation

IE requires that the .htc behavior file must be in the same domain as the HTML page which uses it. If you try to load the behavior from a different domain, you will get an "Access Denied" error. Note that the domain must be exactly the same; that means that http://www.foo.com is a different domain than http://foo.com. http://css3pie.com/documentation/known-issues/#x-domain
