* Fix commit's time
- Use the Committer's `when` as the CommitDate will be modified when the
commit is being moved around in the git tree(e.g. being rebased on top
of newer commits). The Author's `when` is created once and never touched
again.
* Update templates/repo/view_list.tmpl
* Commmt unstaged
* Add fallback
