• Non-largo slimes can now be picked up with an empty hand using right click! This is a stop-gap slime transportation solution until the Vacpack is done.
• Slimes in item form display their diet, allowing for planning/no Jade needed
• Slimes now have a "neutral" happiness where they don't perform positive or negative behaviors. Incubated slimes are born in this neutral state
