New features and enhancements

• mkvmerge: the options –default-track and –forced-track have been renamed to –default-track-flag and –forced-display-flag respectively for improved consistency with other option names & the wording used in the GUI. However, the old names will be supported and recognized indefinitely. What will remain unchanged is the property names for those flags in mkvmerge’s identification output. Existing third-party programs will continue working as they are.
• mkvmerge: added a new option –track-enabled-flag to set or unset the “track enabled” track header flag.
• mkvmerge: MP4 reader: mkvmerge will now evaluate the flags field of the track header atom (tkhd) and set the track’s “enabled” flag accordingly. implementations #3272†
• MKVToolNix GUI: multiplexer: added support for the “track enabled” track header flag.
• MKVToolNix GUI: multiplexer, header editor: added several menu entries & keyboard shortcuts for toggling various track flags of the currently selected tracks, eg Ctrl+Alt+F, D (that’s Ctrl and Alt with F simultaneously followed by D without any other key pressed ) for toggling the “default track” flag. Part of the implementation of #3253†
• MKVToolNix GUI: multiplexer, header editor: added menu entries & keyboard shortcuts for setting the language of the currently selected tracks to one from a configurable list of languages. The shortcuts used are Ctrl+Alt+A, 1 through Ctrl+Alt+A, 0 for the first ten entries of that list (that’s Ctrl and Alt with A simultaneously followed by a digit without any other key pressed). Part of the implementation of #3253†
• MKVToolNix GUI: chapter editor: if the user enters commas in start or end timestamps they will automatically be changed to points as the decimal separator, allowing for easier copy & paste from other programs/sources. Implementation #3273.
