Add SUCCESS Scuba events for each supertd subcommand

Summary: Log SUCCESS events for each subcommand. Include the duration in milliseconds and any summary information that happens to currently be conveniently at hand (for instance: in btd, the counts of immediate and total changes; in verse, the entire VerseExecutionLog).
