gitk: Allow starting gui blame for a specific line
This adds a context menu item to the diff viewer pane that calls git gui blame, focusing it on the clicked line. In case of combined diffs, it also automatically deduces which parent is to be blamed. Lines added by the diff are blamed on the current commit itself. The context menu itself is added by this patch. It would be possible to add the commands from the flist menu to it.
