* Keep track of the current source line number and pass it to Annotate
action.
* Add a 'List Versions' toggle in Annotate editor to prepend a list of
commits that make up the annotated source.
* By default do not show the version list so that annotated line number
could be matched to the source line.
NOTE: VcsBaseEditorWidget::configurationWidget() query is no longer
available, yet Fossil client needs it in order to process the effective
arguments. So we re-implement it in FossilEditorWidget sub-class.
