Incorrect Link header creating

[avtop3]

As I understood from Internet, only relative URIs could be server pushed Also font type resources don't processed as assume.

Feel free suggesting your solution to this. Pull request is welcome

Since this is actually a css, it has been included as css, etc, there is actually only one way to implement this:

1. use registerCssFile with additional special opti$ons to indicate that this asset should be treated like a font
2. implement certain checks and logic here

Something like this instead of preg_match_all (much slower, but working)

$dom = new DomDocument();
foreach ($view->cssFiles as $linkTag) {
    $dom->loadHTML($linkTag);
    $link = $dom->getElementsByTagName("link")->item(0);
    $href = $link->attributes->getNamedItem("href");
    $href = $href === null ? "" : $href->value;
    $type = $link->attributes->getNamedItem("push-type");
    if ($type !== null) {
        $type = $type->value;
    } else {
        $type = "style";
    }
    $this->addPreloadHeader($href, $type);
}
