Updated Eyerok

You must kill both hands before the boss is defeated
NOTE: To correctly spawn eyerok, spawn the left hand!
Fixed: spawning of eyerok two.
Cleaned up the code some - added SetAttackTypes()
Fixed: Both hands should now never be in the same phase, unless it's the
first phase.
Boss now spawns tons of dust whenever hit.
Added some placeholder textures for eyerok.
