	 * 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."
	 * 		</code>
