MKVToolNix GUI: multiplexer: automatically setting the destination file name: added an option in the preferences for using the first source file's directory name instead of its file name as the basis for the destination file name.

Therefore the option to disable the dark mode has been removed. The Windows binaries are now built with said Qt version.

The advantage is that as of Qt 6.5 the 'Fusion' style properly supports Windows 10's & 11's dark application mode.

MKVToolNix GUI: only on Windows: the GUI now uses Qt's 'Fusion' style instead of the deprecated 'Windows Vista' style.

This discards any remaining packets of other tracks. mkvmerge, MKVToolNix GUI's multiplexer: added an option to stop processing after the primary video track ends called `-stop-after-video-ends`.mkvmerge: MP4 reader: the comment & encoder meta data (content of the `.©cmt` & `….©too` atoms) will now be copied over as global tags `COMMENT` & `ENCODER` respectively.mkvmerge: MP4 reader: the title/movie name meta data (content of the `.©nam` atom) will now be copied over as the segment title track header attribute.mkvmerge: Matroska reader: when reading WebM files that use block additions with ID 4 (HDR for VP9) an appropriate block addition mapping will be created automatically.

mkvmerge: the maximum block addition ID track header value is now calculated automatically from both the existing mappings & the actually used block additions in the block groups.

Currently only implemented for Matroska files where it contains the number of cue points.

mkvmerge: JSON file identification: added a child element called `num_index_entries` to the `properties` track element containing the number of index entries found for a track.

Removing block additional data is not possible anymore, as it is often required for proper decoding.

mkvmerge: removed the option `-blockadd`.
