Kobold variety - allows kobolds to have random colors and horns (+ allows RandomSpriteComponent to uh. Actually choose random sprites for specific layers) (#23393)

* kobold variety - allows kobolds to have random colors and horns

* hey lets maybe not crash in this case, lets maybe let the color continue being null in this case

* excuse us vscode what the fuck is this

* brightens kob base, makes kob outline more bold, fixes to the prototype because our code spaghett

* okay yeah angler horns just dont work At All. the floppy kobold ears, however? MWAH. chef's kis

* we've been staring at these critters all day - makes base color line up with the base color of some of the markings
