All organisms now have a small chance to create an entirely new gene while producing a gamete.  Also increased herbivore metabolism and gave herbivores a small chance of eating a plant that they don't match with, since they were dying off too much when a new plant came through and strangled them
Allowed you to change the draw interval with = and -, and toggle drawwing with d.  did a little more tweaks and now the herbivores live forever. I ran them out to 5.2 million and thety are still going strong
