Doesn't need Webdings anymore.
Merge remote-tracking branch 'remotes/origin/lua_experiment' into lua_experiment
osc: Fixed "no duration" case
osc: Clicking on the video title will print the title on normal OSD

For titles that became unreadable due to scaling or too small video.
Or just people with bad eyes.
command: replace some show_ commands with properties

show_chapters, show_tracks, and show_playlist are killed and replaced
with the properties chapter-list, track-list, and playlist.

The output of these stays the same.
