Original Jellyfish

Emulates the jellyfish from Risk of Rain 1. Jellyfish have a relatively low amount of damage: (5, +1/level) which is supposed to scale with their normal nuking suicide. Beetles scale better: (12, +2.4/level). So I scaled up their damage, which lets them deal between 2-6 damage very early (Commando has 110 health).

Also included is an experimental localization for configs for Spanish, Japanese, and Russian. As long as the game is launched in the selected language with no config file (deleted or otherwise), then it will replace the names and descriptions with ones for the defined language. It doesn't support hotswapping, though.
