Removes a very large amount of world loops.
Adds a macro to painlessly generate a global list, and the needed code to modify the list when an object is made or deleted automatically.
Cleans up some commented out code.
Gene masks (like for plant genes) used unpadded num2hex on a random
number 0-255. This had the (technically ok) result of masks for values
1-15 being a single character but also had the (not ok) result of the
mask for value 0 being the empty string. This only happened to 1/256 of
genes, so was easy to miss.
This change pads all of them to 2 characters so this issue won't happen
and to line things up nice.
While I was rooting around in hydroponics code, I saw that a list was being regenerated with UI interaction, so I threw the list into the plant controller.
No proper sprites for the Floral Somatoray's new mode yet, but it uses the gun sprite from mutate mode, and the projectile sprite from yield mode.
