Context Navigation

The initialization of layer 0 is done similar to other algorithms where general initialization is done in the algorithm itself and variables used and produced during the main-loop is initialized in the main-loop-operator.
The GeneralizedRankSelector is used as default selector because it generally works the best (rank compensates the large quality range of multiple layers and high selection pressure via pressure-parameter). Proportional selection performs very badly because the selection pressure is too low for ALPS.
Concerning ReduceToPopulationSize in the EldersEmigrator, the behavior it is not completely clear in the original paper. Reducing the population to the population size seems the more logical way, therefore it is default. An empty layer could happen in extremely rare situations, but it never happens to me so far.
Concerning opening a new layer, when taking a closer look at the ages, all individual tends to be as old as possible, in the standard version with AgeInheritance==1. That means they usually get too old in exactly after the generation the AgeLimits for the current last layer states. This way it is not necessary to check if any individual becomes too old for the current last layer. For AgeInheritance<1 it can happen that there would actually be no need to open a new layer; however, it will be opened anyway.

#1674

ProtoBuff QualityMessages
- Changed the QualityMessage to be able to be used for single- and multi-objective problems.
- The new SingleObjectiveQualityMessage and MultiObjectiveQualityMessage now "inherits" from QualityMessages to be able to be used in a polymorph manner.
- This is done via protobuf's nested extensions (see http://www.indelible.org/ink/protobuf-polymorphism/).
EvaluationCache
- The EvaluationCache now now stores the QualityMessage instead of a single double. This way the cache can be used for single- and multi-objective problems and additionally opens the possibility to extend the quality message with any data. (previously extended data was lost when the cache was persisted and loaded again)
- When deserializing an older version of the cache a new single objective quality message is created from the double value. This way, no compatibility is broken and version must not be incremented.
Adapted the ExternalEvaluationProblem to the changes of the EvaluationCache and the QualityMessage.
Added a MultiObjectiveExternalEvaluationProblem on basis of the ExternalEvaluationProblem and added a IExternalEvaluationProblem interface.

#2442: Merged files from trunk and updated project file. Implemented missing operations in the CompiledTreeInterpreter: Integral, Derivative, Lag, TimeLag. Adapted lambda signature to accept an array of List<double> in order to make it easier to work with compiled trees. Changed value parameters to fixed value parameters and adjusted interpreter constructors and after serialization hooks. Removed function symbol.

From the performance point of view, compiling the tree into a lambda accepting a double[][] parameter (an array of arrays for the values of each double variable), accessed with Expression.ArrayIndex is the fastest, but it can be cumbersome to provide the data as a double[][]. Therefore the variant with List<double>[] was chosen. Internally, for each variable node the List's underlying double array is used, result in an overall decent speed compromise.
