Add missing changes to stable

[ascheibe]

There are some problems where stable and trunk diverge because of missing or wrong merges:

• BiasedMultiVRPSolutionCrossover/BiasedMultiVRPSolutionManipulator: There was a commit (r10474) in #2146 that did get merged with another ticket (#2119) and another commit (r10504) that fixed a bug introduced in the previous commit. I think they were merged in the wrong order. In any case these 2 files differ from trunk and should not.

• RandomEnumerable/RandomEnumerableSampleTest: It seems that r10646 and r10503 got lost somewhere or were forgotten in the merge.

• No problem but inconvenient: In the merge into stable of #2143 r10955 was forgotten. This commit adds a line in SymbolicDataAnalysisSingleObjectivePruningAnalyzer, another one that got merged deleted this line again. Therefore when merging trunk into stable, this line gets re-added.

I detected these problems by merging the complete trunk into stable. There are of course some differences that are ok:

• the persistence changes that won't make it into this release (#2096, #1802)
• the conflict in the VRP sample (will be fixed when regenerating the samples for the release)
• the tree matching stuff (#2164)

Everything else should be the same between trunk and stable.

r11168 merged r10955 into stable

r11169 reverted r11168 by hand to get a consistent trunk/stable

abeham: As discussed these are the changes. Maybe you can have a quick look at it but I think I got everything and it should now be fine.
