MKVToolNix GUI: multiplexer: when adding Blu-ray playlists the dialog allowing the user to select the playlist to add will now show audio & video track properties as well (pixel dimensions for video sampling frequency, channels for audio).

MKVToolNix GUI: multiplexer: added the option `-stop-after-video-ends` to the dialog for additional command line options. MKVToolNix GUI: multiplexer: when adding files the GUI can automatically enable the 'forced display' flag for subtitle tracks if the file name contains the word 'forced' delimited by certain characters (configurable).
