-Fix up manually supressed axis labels. Conceptually, manually supressed axis labels do not
work well with shared axis boxes, so supressed axis label settings are ignored while
in a shared axis box.

-Allow data dialogs to not have 'edit multiple' in the UI, and then remove it from the
vector dialog. The 'edit multiple' capabilities of the vector dialog are achievable in
the change file dialog and the change sample range dialog, so perhaps edit multiple is
never needed for the vector dialog.
