Rebalances K'ois Mycosises (#4224)

By the request of BygoneHero with some prodding on my part, the gestation periods for both K'ois Mycosis and Black K'ois Mycosis have been severely reduced. K'ois Mycosis will now take 7 and a half minutes to reach maturity, and Black K'ois Mycosis will take 10 minutes to reach maturity. Previously it was 30 minutes and 20 minutes respectively. I believe that these new values are more appropriate, plus it means people won't die before they reach the final stage, for better or for worse.
