    Sort the network graph both by commit date and topographically. · b44eaf8e

    - Previously, we sorted commits by date, which seemed to work okay.
    
    - The one edge case where this failed was when multiple commits have the same
      commit date (for example: when a range of commits are cherry picked with a
      single command, they all have the same commit date [and different author
      dates]).
    
    - Commits with the same commit date would be sorted arbitrarily, and usually
      break the network graph.
    
    - This commit solves the problem by both sorting by date, and by sorting
      topographically (parents aren't displayed until all their children are
      displayed)
