Realistic Horse Genetics

Added non-dun 1

Added snowdrop dilution

Added genetic testing by right clicking a horse with a book (can be disabled in the config)

When horses are right clicked with a saddle or armor and they're not already wearing something in that slot, they equip it instead of opening the inventory (can be disabled in the config)

Changed the default value of useGeneticStats to true now that there is a way to get information about them. If you did not already have it set to true before, this will change your horses' stats. If you want to avoid that and don't want the new genetic stat features, start up Minecraft with this version and close it at the title screen, then set useGeneticStats to false in the config, then proceed.

Some small adjustments to how genetic stats are calculated, including the addition of immune system genes that give a bonus to genetically diverse (not inbred) horses.

Minor fixes for some colors being the wrong shade
