JImageHelper to handle base64 encoded streams

I found that with the use of base64-encoded data streams of image files it should be possible to integrate the creation of such streams and that JImageHelper is the best place to request it from. So i added two new methods - toBase64 and fromBase64. While the former method generates a ready to use base64-encoded data stream that can be used with an `<img/>` element's src-attribute as well as with CSS the latter takes such a stream and writes it into an image file.

The methods can be tested the following way:

```
// Array of different input types and input path scenarios to show the paths are properly handled
$files = [
   'http://www.example.com/images/powered_by.png',
   '/abs/path/to/joomla/images/powered_by.png',
   '//images/powered_by.png',
   '\\images\powered_by.png',
   'images\powered_by.png',
   '\\abs\\path\to\joomla\images\powered_by.png',

];

// Iterate over the files array and output every image to your browser
foreach ($files as $f)
{
   echo '<img src="' . JImageHelper::toBase64($f) . '" border="0" alt="Image"/>';
}
