VCard::addMedia() 'Content-Type' validation should be case insensitive

[dGilli]

if (array_key_exists('Content-Type', $headers)) {
    $mimeType = $headers['Content-Type'];
    ...
}

In VCard::addMedia() on line 239 and 240, the 'Content-Type' lookup should be case insensitive.

Header content-type: image/jpeg will throw unexpected error.

I had exactly the same problem. I think adding array_change_key_case() would be ideal.
After that, every header can be accessed using its lowercase name. I opened PR #210.

$headers = array_change_key_case(get_headers($url, 1));

if (array_key_exists('content-type', $headers)) {
    $mimeType = $headers['content-type'];
    if (is_array($mimeType)) {
        $mimeType = end($mimeType);
    }
}
