add a --phase flag to summary
*Created originally on Bitbucket by [marmoute (Pierre-Yves David)](https://bitbucket.org/%7B44ceb89a-1cda-4c13-bf87-294dddcd719b%7D/)* This flag would display the phase of changeset (the same --id add short node) (I'm starting to think we just want a --template support here)
