allow users to set scroll state...

allow users to set scroll state and persist that state in metadata. When user toggles the scroll state, the choice is remembered and persisted. There are three states: - 'auto' (default, only state in master) - true (always scroll if above minimum_scroll_threshold) - false (never scroll) true or false is persisted in cell.metadata.scrolled. "auto" may be persisted, but isn't currently because it's the default state.
