update rollback to rollback all migrations that were applied by the migrate command about migratus

[ndrluis]

what about something like rails migration?

When you call only rake db:rollback rails rollback only the last migration but if you want to recover more migration you can call rake db:rollback STEP=3 and rollback three steps.

I'd be ok with that, Rails is true and tested so I don't see any reason not to follow step. :)

It would be nice to also have the option to rollback the last set of migrations that was applied as well though. I find that's fairly common, if I run a set and it breaks something, I probably want to roll back the whole set at that point. Could be something like rollback all

[ndrluis]

@yogthos IMO could be better to be more explicit, like rollback last-migration-batch

[yogthos]

I'm not too attached to the wording there, any chance you'd be interested to take this one on? :)

[ndrluis]

@yogthos I don't have a lot of experience with clojure but I can try :D

[yogthos]

I can definitely help out with any questions and help out with getting the feature going
