Previously in history views, revisions were ordered according to the
BFS traversal of the revisions DAG.

This commit adds three new ordering type modifying the history display:

  * Committer date ordering: revisions are displayed in reverse chronological order
    of their commit date

  * DFS: revisions are ordered according to the DFS traversal of the revisions DAG

  * DFS post: revisions are ordered according to the DFS post traversal of the
    revisions DAG

The four types of revisions ordering can be easily switched through the UI.
