#2709

• Added Check Inputs/All/None buttons instead of showing disabled buttons of the ItemCollectionView.
• Removed the PreprocessingCheckedItemListView. A standard ListView is used instead.
• Fixed slow updating when simultaneously (un-)checking multiple variables in the chart views. (currently only works by using the new buttons)
