* Add red fairies; tweaks to blue fairies and circles * Add more fairies and a simple enemy archetype system Note that existing stages not utilizing the new enemy spawning system will have a visual regression - fairies will not have their magic circles and particle effects visible. These are no longer implemented by the enemy visual rules and require additional setup from the new spawner wrappers. All stages should be converted to the new system. Also improved old fairy sprites * enemy_classes: rebalance HP * enemy_classes: add EnemySpawner typedef * items: add ITEMS() shortcut macro for use with enemy spawners
