Add FIFTEEN–LOVE, a 19-second umpire-scored spot

cut.py --cut score: no interview audio, only the game's own recorded
umpire. "Spectators are reminded to remain seated, especially the
deceased", then a love game called against the viewer, one member's stare
per point under a broadcast score bug, "Game. Set. Massacre." on black,
and "This match is still in progress" over the logo. cut.py now holds
named cuts, each with its own build folder and output file.
