Add a 36-second cutdown of the trailer

Browse Source 
cut.py --short builds a social-length version from the same takes: one
line per witness cut inside their takes, then the challengers beat,
"Quiet, please", "Play", the splat and Reg's stinger. Each cut keeps its
own build folder and output file, so cut 2, cut 3 and the short all stay.
words.py gives local Whisper word timestamps for cutting inside lines.
