#2698 Forgot to uncomment abstract keyword.

16:20 Changeset [14381] by pfleck

#2698

Refactored CheckedVariablesView out of the ChartView to allow reuse of the checked variables list.
- The new list visualizes the non-input/target variables in gray.
- Added context menu to quickly (un)check all variables or only the inputs+target variables.
In the Multi-Scatterplot
- New structure and layout of the single charts to support fixed header rows and columns (for the variable names). Instead, removed the legend of each plot for better usage of plot area.
- Adapted the new CheckedVariablesView (but hidden until (un)checking is implemented).
