[issue8] Add "upgrade --stepped" to shell mode

[Mauricio Teixeira (netmask) at Labix Tracker]

New submission from Mauricio Teixeira (netmask) <mteixeira at webset.net>:

Is it possible to add "stepped" upgrade in shell mode? I have a slow system and
prefer to use shell mode because of not loading/saving cache all the time, but
when I do upgrade this so handy feature is missing.
