[Bug] GSimpleGA and Selectors.GTournamentSelector

[cristianocca]

Having the following:

ga = GSimpleGA.GSimpleGA(genome)
ga.selector.set(Selectors.GTournamentSelector)

There 'tournamentPool' is not working.

I have added it on both, the genome:
genome = G1DList.G1DList(N)
genome.setParams(rangemin=0,
rangemax=2,
tournamentPool = 5
)

And ga.setParams(tournamentPool = 5)

However when GTournamentSelector tries to get that param, it can't find anywhere. I have debugged the code and it is quite messy, the same get/set operations are in GenomeBase, GPopulation, and GSimpleGA, some params are fetched from one class, some from others, you don't really know where to set each one of them.
