Random Configs

Added `AdditionalVariantGroups`. With this, you can add additional cases of variant mating compatible across completely different species. For example, to make dodos compatible with wyverns and vultures with jerboa and mantis, you use `AdditionalVariantGroups=Dodo:Wyvern,Vulture:Jerboa:Mantis`. Groups separated with commas, and the Dino Tags separated with columns.
