Message:

#1758: Reimplemented functionality to load new problem data to data analysis solution and redesigned the according views.

• Added setter for the target variable of regression and classification problem data.
• Added functionality to check the compatibility of problem data.
• Added functionality to adjust the properties of a problem data.
• Added flowLayoutPanel with according buttons for loading a new problem data, simplifying and exporting data analysis solutions.
• TradingProblemData currently throws a NotSupportedException when the properties should be adjusted.
