Three new heroes: giant, fairy spy, battle mage

- giant (from wave 6): slow and enormous, smashes doors three times as hard and wrecks traps by standing next to them
- fairy spy (from wave 3): flies, finds the dungeon's traps (marked with a glint) so the heroes wreck them, and heals heroes around it
- battle mage (from wave 4): throws fireballs with splash and blasts reinforced walls (steel resists him better)
- sprites, bestiary texts EN/DE, test: fairies find traps, giants wreck them
