The Grovelling-to-the-Chef Games (monkey cubes and meat spikes) (#2117)

* Rehydratable component -> monkey cubes now have some of their behaviour

* Placeholder kitchen spike entity

* KitchenSpike component: the kitchen spike now has basic functionality

still placeholder sprite though

* Kitchen Spike: Import meatspike assets from CEV-Eris

* Kitchen Spike: Actually use sprites somewhat

* Kitchen Spike: Forgot I removed the MeatParts property from Butcherable

* Monkey cubes: Use IReagentReaction even though it doesn't quite work yet. Butcherable: remove imports

* Monkey cubes/Rehydratable: Re-add ISolutionChange

* Update Resources/Prototypes/Entities/Constructible/Ground/kitchen.yml
