Added multi-threading to the first run of the genetic algorithm

Note: only the first run, as subsequent runs have a much smaller population, so the overheard of creating threads slows them down
Also added up-to-date ThirdAgent.jar file (doesn't include multi-threaded GA) & random level seed to bat file
Minor changes
