Shuffle manipulation treats the training and test partition separately

[mkommend]

The data preprocessing view provides the functionality to shuffle the data. While doing so, the defined training and test partition are shuffled separately, which in most cases has no effect while modeling the data. Therefore, the user should be able to specify if the partitions should be shuffled separately or the whole data should be shuffled, where the later should be the default option.

r11380: Added a checkbox in the properties section of the shuffle data tab in the ManipulationView to specify whether the problem data should be shuffled as a whole or separately for each training/test range. Modified ShuffleToIndices methods accordingly. Also fixed very small typo in ManipulationContent.cs

r11381: Forgot to commit changes to ManipulationView.cs.

Reviewed r11380.

I'm not happy with the methods in interface IManipulationLogic.

void ShuffleWithRanges(bool shuffleRangesSeparately); 
void ShuffleWithRanges(IEnumerable<HeuristicLab.Data.IntRange> ranges);
void ShuffleWithRanges(IEnumerable<HeuristicLab.Data.IntRange> ranges, bool shuffleRangesSeparately); 

Instead I think the following would be better:

void Shuffle(); 
void ShuffleWithRanges(IEnumerable<HeuristicLab.Data.IntRange> ranges);

If reasonable, please adapt the implementation accordingly.

r11403: The Shuffle method needs a bool parameter to be passed from the view (checkbox whether to shuffle with ranges or not). I combined the three methods into just one method void Shuffle(bool shuffleRangesSeparately).

r11537: Merged r11380, r11381 & r11403 into stable.
