Title: Named Backup Functionality

Made a few alterations to support named backups. With this PR, we'll be able to do this:

$image = Image::make('/path/to/image');
$image->backup('original-state');

$image->crop()->resize();

$image->backup('proper-size');
$image->greyscale()->save('bw-version.jpg');

$image->reset('proper-size')->save('color-version.jpg');

Example doesn't really makes much sense as we could just save color version first but it's just an example. Focus on the functionality.
