pullrequest/compare: add logical changeset index to clarify the order

Is the parent-most changeset in a changeset the one at the top or at the
bottom? When the revision numbers are not shown, it is not obvious to
determine this.

This commit adds a logical changeset index to the commit list in a
pullrequest or compare view. The index starts at 1 (the parent-most commit)
and has no relation whatsoever with the commit hash or revision number.
