Area spells are finally animated

Area spells now have a real visual identity. The Dorken's War Cry unleashes an atomic mushroom cloud, and the Krix's Arcane Explosion comes in three colorful variants.

For bosses, the warning of an area attack is now an energy core that swells before impact, replacing the old red circle.

Boss animations were also reworked: stable size from one pose to the next and feet properly planted on the ground.
