Added 13 types of slimes/changed slime reproduction to give mutation chances on birth.

Added 13 core types with a mix of old and new reactions. Each slime has its own core type/reaction.

Added plasma sheets/a grinder to xenobio.

Added Phoal's slime people sprites.

Added simple animal pet slimes (one of the core types allows you to obtain them).

Updated the changelog

Still to come: slime types having their own temperature resists/special attacks.

This is all probably unbalanced as well but we'll see how it goes.
