Decreased the filesize by:
- using a more suitable VTF format (RGB888 over RGBA8888)
- disabling mipmaps (mipmaps aren't present in ULTRAKILL)
KITR's textures no longer look awful when your game's texture quality is at Low.
The textures also now have Clamp S and Clamp T, which might help it look better

kitr no longer appears in entities

fixed the model, nov it should be EXACTLY like in the game

kitr now kills attacking players and npcs; kitr now will seek and destroy any npcs (hostile or not)

disabled texture filtering (more ultrakill-ish textures)
