There was no need to use image-files for the graphs, so lets drop them.
At the same time, fix scaling of the graphs so that the full width is
used only if atleast 100 LOC are changed in one of the files.

The diffstat is calculated against the leftmost parent of the commit. This
gives nice information for "normal" merges while octopus merges are less
than optimal, so the diffstat isn't calculated for those merges.
