Allow gitGraph commit.id to be set

Is your feature request related to a problem? Please describe. I am always pushing for people to move from SVN or other types of no-versioning-systems to git. To do this a graphic representation does wonders. Mermaid is in a form that makes lends itself to a somewhat
