Lower MovesUpdater debounce from 1500ms to 500ms

In normal typing, the debounce only delays the last letter of each run — a
cell-change forces an immediate flush for every prior letter — so the old
1500ms value meant the trailing keystroke of each word a collaborator typed
took roughly a second and a half longer to surface than the rest. 500ms is
still well clear of a typical typist's intra-word pause, so the number of
record writes per unit of typing is essentially unchanged.
