#228 Add support for default and forced track flags for mkv files

[myarmor]

MKV files can have forced and default track flags (and often do), can you please add support for them to MediaInfo.dll and MediaInfo?
MKVMerge can determine these for a .mkv file, so it should be doable.

I'm posting this request in accordance with your answer at https://sourceforge.net/projects/mediainfo/forums/forum/297610/topic/3404391

I'm not sure of OGM files has support for the same, but it isn't too unlikely.

OGM does not have this, unfortunalty (or I don't know where it is... If you have samples of OGM files with forced/default track, I am interested in)

Just wanted to chime in and say I'm also looking for this feature. I use MediaInfo.dll in a project I'm working on, and I'd really like to be able to get these two flags from MKV files. When dropping an MKV file into MKVMerge GUI, these flags are correctly set to the current values for the tracks, so this info must be in the MKV file somewhere.

MKVToolNix Gui has a "Properties" pane which shows these two flags, as well as several others, most notably "Commentary" and "Visual Impaired". Mkvpropedit allows the setting of these flags with "--set flag-commentary=1" and "--set flag-visual-impaired=1" to name just the two. Is there any way to get at these flags via custom code that makes calls to MediaInfo.dll?
