webplugin: MediaPlayerTitleChanged is currently useless
I have seen now, that this event is'nt asynchronous. (see https://forum.videolan.org/viewtopic.php?f=32&t=90384#p299011) So this event is useless for the plugin and it will never be fired, because there is no method implemented to set a title over libvlc_media_player_set_title(). Should we remove this event, or should we add methods to get/set the title?
