Feature request: Open up CORS by default

[royduin]

I've added

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: *');
header('Access-Control-Allow-Headers: DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range,Authorization,X-ReCaptcha,Store');

if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    http_response_code(200);
    exit;
}

At the beginnen of the server.php which seems to do the trick. Handling this in the Nginx config is also possible but then we've to catch the OPTIONS request there for the CORS preflight requests.
