[DEV] The Rat Skull Returns in Shattered v2.4.0!

After almost 10 years, the rat skull will finally return in Shattered Pixel Dungeon v2.4.0 as one of the game's new trinkets! It was formerly a quest item that I removed way back in v0.2.1. Now the skull will passively boost the chance for you to encounter rare exotic enemies like albino rats or crystal mimics. This means a bit more challenge, but also more rare loot!
