Allow exif data of images to be read from server

[kartik-v]

initialPreviewConfig will now read an additional property exif that will get the exif object containing the exif properties for each uploaded image. This will be used by the plugin to auto detect and orient the image preview.

An example of PHP server code as used in ajax demo 6 that will return the JSON config to the plugin after upload:

$img1 = '/uploads/images/image-01.jpg';
$img2 = '/uploads/images/image-02.jpg';
return json_encode([
    'initialPreview' => [$img1, $img2],
    'initialPreviewConfig' => [
        ['caption' => 'Image 01.jpg', 'size' => 139823, 'key' => 1, 'exif' => exif_read_data($img1)],
        ['caption' => 'Image 02.jpg', 'size' => 339649, 'key' => 2, 'exif' => exif_read_data($img2)],
    ]
]);
