[issue7] Add quit option to stepped mode

[Mauricio Teixeira (netmask) at Labix Tracker]

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

When installing/upgrading the system in stepped mode, after each group of
packages smart asks to confirm the changes. If "n" is given, it asks for the
next group, and continues to the end. I would suggest to add a quit ("q") option
so that one can gracefully abort the proccess at any time without having to ctrl+c.
