I've added these functions to media player :

• setTime -> allow to seek in a file at a position in ms (libvlc_media_player_set_time)
• getTime -> get file position in ms (libvlc_media_player_get_time)
• setPosition -> allow to seek in a file at a position in percent (from 0.0 to 1.0) (libvlc_media_player_set_position)
• getPosition -> get file position in percent (from 0.0 to 1.0) (libvlc_media_player_get_position)
• setX11Window/setWin32Window/setOSXWindow -> allow to set a window for libvlc output. Useful if you don't want to be limited to directfb output (node-qt, node-x11).

I've fixed types in libvlc_media_player_set_time and libvlc_media_player_get_time bindings by replacing "longlong" by ref.types.int64.
