Add support for Javascript Typed Arrays

[GoogleCodeExporter]

Glancing over the source I've noticed that crypto-JS does not seem to support 
Javascript typed Arrays 
(https://developer.mozilla.org/en/JavaScript_typed_arrays)

Adding support for this would probably speed up the library a bit.

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?


Please provide any additional information below.

Hi, Oliver. Unfortunately the typed arrays are not cross-browser compatible. 
And in fact the browser most in need of a speed boost is the same browser that 
doesn't support the typed arrays.

Hi Jeff

Sure they are not universally available but since you already got the 
abstraction for WordArray.create it should be possible to leverage typed arrays 
when available.

The latest release includes the ability to create WordArrays from typed arrays. 
You'll need to include an additional component -- lib-typedarrays.

<script 
src="http://crypto-js.googlecode.com/svn/tags/3.1/build/components/core.js"></sc
ript>
<script 
src="http://crypto-js.googlecode.com/svn/tags/3.1/build/components/lib-typedarra
ys.js"></script>
<script>
    var wordArray = CryptoJS.lib.WordArray.create(uint8View);
</script>

You can create a WordArray from any of the typed array views -- Int8Array, 
Int16Array, etc. -- or from an ArrayBuffer, or from a DataView.

This is likely as far as this library will go with typed arrays until they 
become more cross browser compatible.
