Setups toolbar

The post-processing save icon turns red if the post-processing setup is changed. It also turns red if settings in the chart files (all the settings in Plot->Chart Settings for Active Plot) are changed, but there are cases where this will not happen, e.g. on File->New… and when loading WinMLS. Also when moving toolbars or turning them on/off, the post processing setup file toolbar does not give indication that the setup is changed (red icon).
