v0.0.4 changes

So, it's been a lot of work in a small amount of time (I don't remember if I slept or not...)

+ Added 2 new fights and 1 boss fight (good luck...)

+ Added new items made of monster parts.

- Reworked the map and added fights in rooms. Not that the chests in the HUB are not filling while you're in fight rooms or in combat.

- Reworked rarity system : Order and monster paths (Order equipments are obtained in chests or direct evolution from order equipments, Monster equipments are obtained when crafting with monster loots). Order rarities = Beginner < Apprentice < Adept < [Surprise] < [Surprise]. Monster rarities = Furious < Alpha < Gamma < [Surprise] < [Surprise]

- Reworked a bunch of things and a lot of balancing.
