R0n1n mod

It literally just adds to R0n1n.
More specifically, add 2 entities: R0n1n (a neutral entity) and bullet (which is fired by her weapon), and 3 items: R0n1n's egg, the bullet, and his pistol.
R0n1n is naturally generated by the world, and drops his pistol. The bullet has no function yet, as the pistol does not use it.
The R0n1n model and its functions are based on TGH's mascot.
