Corgi UI and player-controlled behaviours

Created by: DeityLink

-Corgi now have their very own HUD -Corgi health upped from 20hp (simple_animal default) to 30hp (still half of a MoMMi's health) -player-controlled corgis can now eat food by clicking on it. They can swallow a food\snack item after 5 bites. Doing so gives them back 1/6 of their full health (5 HP of 30HP) -when player-controlled, simple_animals won't randomly move or speak anymore (this behaviour now only happens when ckey == "null") -player-controlled corgis now have a verb that allows them to perform Ian's high speed tail chase/dance. Can be performed while moving for extra kek.

I plan on giving players a way to play as corgis, something based on the combined use of a soulstone and a lazarus injector. In the meantime, it's still useful during adminbus.
