[Plugin: Link Library] Type of favicon files is faulty

Hello, if you press “Generate Favorite Icons and Store locally” it save for thumbs and favicons allways .JPG files. But favicons are native .PNG files.
I have make a change to your code to solve this problem.

Change code:

$img = $uploads['basedir'] . "/" . $filepath. "/" . $linkid . ".jpg";
$status = file_put_contents($img, file_get_contents($genthumburl));

if ($status !== false)
{
$newimagedata = array("link_id" => $linkid, "link_image" => $uploads['baseurl'] . "/" . $filepath . "/" . $linkid . ".jpg");

Replace with following code (or a better solution):

if ($mode == 'thumb')
{
$img = $uploads['basedir'] . "/" . $filepath. "/" . $linkid . ".jpg";
}
else
{
$img = $uploads['basedir'] . "/" . $filepath. "/" . $linkid . ".png";
}

$status = file_put_contents($img, file_get_contents($genthumburl));

if ($status !== false)
{

if ($mode == 'thumb')
{
$newimagedata = array("link_id" => $linkid, "link_image" => $uploads['baseurl'] . "/" . $filepath . "/" . $linkid . ".jpg");
}
else
{
$newimagedata = array("link_id" => $linkid, "link_image" => $uploads['baseurl'] . "/" . $filepath . "/" . $linkid . ".png");
}

Thanks for your great work.
