Spellbook rework, defense nerf and balance changes!

GENERAL CHANGES:

REWORKED SPELLBOOK MANA SYSTEM:
- Spellbook mana system felt kinda weird. Either you get to spam your spellbook every turn or it was almost useless. I decided to change that all spellbooks now gain 1 mana the first time you attack a bug each turn. This way every spellbook has consistant way to generate mana, but there are still relics that let you get it in more funky ways.
- Of course, because of this change, all spellbook mana costs and the amount of mana each relic generates were updated.

BALANCE CHANGES:
DEFENSE is very strong attribute. You almost required to invest a bunch of points into it to have a good time and not immediately explode on third zone. But balancing defense is very tricky. It's damage reduction effect can't go lower because it's already at 1. My solution is to increase all bug damage, player healing, max health by about 50%. That way defense gets indirectly nerfed and as a bonus, some strong relics that apply frost or increase max health get toned down too. Let me know how these changes feel, I'm really curious
