Improve CSV import for data analysis problems

[sforsten]

When importing a data analysis problem from a csv file, it should be possible to shuffle the data and to select how much should be training and test.

For classification problems, it also should be possible to decide whether to normalize the dataset in a way, so that from every class exactly the same amount of samples are imported, or to leave it as it is.

Reviewing comments:

• Place OK / Cancel button on the right side of the import dialog.
• CancelButton hides a member inherited by Form. Use a different name for the button.
• DataAnalysisImportTypeDialog: Is it really necessary to use a BindingList.
• Improve ErrorHandling of ConsumerViews (catching of Exception).
• Shuffling of classification problem data doesn't work correctly!
• There should be a checkbox if the distribution of class values should be taking into account during the shuffling.
• Evaluate if it is possible to import files although they are opened in other programs (e.g., Excel). Currently this is not possible.
• License header is missing in .designer files.
