qt4: make dnd to accepts network-urls

drop toNativeSeparators-usage (shoudln't break win32, but then again this could
be my application for the 'stupid win32 breakage of the year' ;). This allows
for example drag youtube links to vlc playlist directly.

Parse also dropper text if it has valid url if we don't have urls on drop ( from browser addressbar for example you get text ).
