In the CrossValidationView the value for the samples end field is not updated when a new problem is loaded

[abeham]

Samples Start and Samples End remain the same even though a new CSV was loaded in the problem.

Expected:

• The sample range for cross validation adjusts to the new range of samples

Reproduce:

1. Create a Cross Validation
2. Create a new algorithm (e.g. LR)
3. In the problem load a new CSV

r8965: Added missing event registration in AfterDeserialization of CrossValidation and clean up code if a problem changes in the crossvalidation. Additionally, I removed explicit calls to OnReset in the Load methods of IDataAnalysisProblems the reset event is automatically fired when the problem data is changed.

r8966: Reversed changes in OnlineMeanAndVarianceCalculator as this must be first discussed with gkronber and should be tracked in a separate ticket.

Even after r8965 the fields for samples start and end are not updated when the data set is changed (for instance by loading a new problem instance).

r8969: Corrected event registration for problem changes in CrossValidation.

r8970: fixed formatting

Tested r8969:8970 and couldn't reproduce the problem. Thanks for fixing this!
