When auto-updating `summary`, reactions were not being removed for listing types of transfers of which there were none. Now that's fixed. e.g. if the number of downloading transfers goes from 1 to zero, the downloading reaction will be removed the next time the output is updated.
Repeat option for `summary` and `list` commands
More filters: stalled, running (non-zero rate), error (and types of error), verifying data, queued, public/private (tracker)
Added option to verify data to `modify` command
Added more info to summary.
