Stuff for the Biogenerator

1.Added an option to dispense 50 milk and 50 cream and 5 monkey cubes, since it is relatively annoying for botanists to make small amounts upon small amounts. So now it gives a x5 button.

2. The Ez-nutrient, and the other 2, always only made 3 of it instead of 5 when you used the x5 button. That has been fixed.

3. Added Plant-B-Gone and Pest Spray to the biogenerator.

I tested everything locally, and everything works as intended.
