Decouple DataPreprocessing from SymbolicDataAnalysis

[pfleck]

Currently, the DataPreprocessing only works when creating any SymbolicDataAnlysis Problem, then load the data and then open start the DataPreprocessing. However, the DataPreprocessing could be used independently from any problem. In addition to start preprocessing an existing dataset, it should also be possible to start the DataPreprocessing “from file” or open a “blank” data.

r13508

• Enabled type selection for creating/importing/exporting/applying.
• Deleted unnecessary interfaces.
• Reorganized source files of DataPreprocessing.

r13514

• Enabled pasting values with headers into preprocessing. The headers will be extracted and the columns renamed.
• Removed an unnecessary interface.
