Moment titles from a scene note: no "The streamer is", no dangling end (#603)

OP OpenVibers committed 10 days ago · 5ecb928c82 · 2 files, +10 −2

Two of the home's four moments (11-03) were titled "The Streamer Is Livestreaming From A Low-Angle POV Inside" and
"The Streamer Is Playing Fortnite, Sprinting Through A Cave-Like". "The streamer is …-ing" is dropped (the words go to
the moment), and inside/through/behind/like/that/… and a "-like" adjective join the words a title may not end on.
