Fitness function should be evaluated only for new chromosomes

[GoogleCodeExporter]

It is required to recalculate fitness value only of new members of the 
population. If input data don't change during solution search, we do not 
need to recalculate fitness of the entire population, what leads to 
decreasing performance.

Issue 1 fixed - only new members of the population are evaluated. Random 
generation 
of new chromosomes was removed from selection algorithms, but implemented in 
population class.
