Implement ALPS with Offspring Selection

Description

Implement ALPS with an offspring selection genetic algorithm (ALPS-OSGA).

There already was a ticket (#2375) to implement ALPS-OSGA but it was closed since the combination of ALPS and OS seems to perform badly. However, it was decided to still offer an ALPS-OSGA implementation for further research.

Reviewed r13402: I have one comment: In AlpsOffspringSelectionGeneticAlgorithm.cs is some commented out code in line 286/287/316/472/776. All have to do with the SelectionPressureTerminator. Please either remove the code or make it work. Other than that I have no further comments.
