MKVToolNix GUI: job queue: added a new setting in the preferences' "job queue & job status" section that, when enabled, will cause the GUI to remove all output files created by jobs that are either aborted by the user or that end in an error. Implements #2614.
mkvmerge: when splitting by chapters the user can now split by chapters coming from one of the appended files, too. Fixes #2625.
mkvmerge: AAC reader: fixed reading codec parameters (channels, sample rate) if a file starts with garbage that includes valid-but-bogus AAC headers. Fixes #2622.
MKVToolNix GUI: Hebrew was added to the list of often-used languages so that it can be selected by default again. Fixes #2610.
MKVToolNix GUI: when updating the GUI's settings from v37.0.0 or older, the GUI checks if the list of often-used languages equals the built-in list from v36.0.0. If it does, it will be updated to the built-in list changed in v37.0.0. Fixes #2611.
