* jQuery BASE64 functions
* 
*      <code>
*              Encodes the given data with base64. 
*              String $.base64Encode ( String str )
*              <br />
*              Decodes a base64 encoded data.
*              String $.base64Decode ( String str )
*      </code>
* 
* Encodes and Decodes the given data in base64.
* This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.
* Base64-encoded data takes about 33% more space than the original data. 
* This javascript code is used to encode / decode data using base64 (this encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean). Script is fully compatible with UTF-8 encoding. You can use base64 encoded data as simple encryption mechanism.
* If you plan using UTF-8 encoding in your project don't forget to set the page encoding to UTF-8 (Content-Type meta tag). 
* This function orginally get from the WebToolkit and rewrite for using as the jQuery plugin.
* 
* Example
*      Code
*              <code>
*                      $.base64Encode("I'm Persian."); 
*              </code>
*      Result
*              <code>
*                      "SSdtIFBlcnNpYW4u"
*              </code>
*      Code
*              <code>
*                      $.base64Decode("SSdtIFBlcnNpYW4u");
*              </code>
*      Result
*              <code>
*                      "I'm Persian."
