Dragging a url into the smplayer main window work before the upgrade, now the url can't be dropped.

I assume the problem is that the mime type of the drag event changed.
Currently (after the upgrade) the drag event mime type of a URL (from akregator or kmail) is "text/plain".
I think it should be a list: ("text/uri-list", "text/plain").



Reproducible: Always

Steps to Reproduce:
1. Try to drag a url into a application which only accepts url drops

Actual Results:  
Drop is not possible.

Expected Results:  
Url gets dropped.

A dragged URL from Firefox has following mime type list: ("text/uri-list", "text/html", "text/unicode", "text/plain;charset=utf-8", "text/plain") (Removed Mozilla specific mime types)
