#402 made Effect Controls' rows compact and aligned, as After Effects
draws them, and also added thin separator lines between parameter rows
in Effect Controls and the Timeline, with a Settings > Appearance > Show
Parameter Row Separators preference. After Effects has neither, so the
lines, the preference and the Tokens field go; the compact rows, the
alignment and the automation ids stay.
Saved settings with the old key load as before (unknown keys are
ignored).
Test: ui_parameter_spacing keeps the row geometry, hit target and
nesting tests; the separator tests go with the feature.
