Hopefully passing the GA

Want to pass the GA engine into the evaluator so all genomes are
simulated, but that doesn't appear to be the case.
Removed excess print

Removed a print statement from debugging.
Fixed running without a library

Fixed trying to read a library / summary of previous runs when they did
not exists.
Removed unecessary reimport of data

Removed unnecessary re-import of the previous runs; this assumes that
the dictionary updates work correctly.
Simulating all genomes

Simulating all of the genomes.  If a genome is not simulated in the main
(I don't know how this happens) then it is simulated seperately from the
group.  Hopefully this doesn't happen often, as it is expensive.
Using Tournament Slector

I didn't figure out how to fix the evaluation bug, but I have a nasty
wrap around.
Simulating 10,15,20,25,30 Genomes

Simulating a bunch of genomes.  Not saving the results in the CSV, using
the pyevolve.db structure instead.
