Add "Goto Group" transition trigger

If you have a bunch of steps grouped and you would like the app to jump to the first step of a particular group it would be great if you could just select the group as a target rather than either having to provide the explicit name or the first step of the group as a target.

That way, if either the group name or the first step of a group changes, the respective transition would still stay intact and you would not need to go through the triggers to see if the references are still up to the task.
