We now send the PlayerState in the spawn struct to allow clients
to see other bard animations with instrument to be played if they
zone in after the bard equipped the instrument
OP_WeaponEquip2 and OP_WeaponUnequip2 renamed to OP_PlayerStateAdd
and OP_PlayerStateRemove
Still needs work: Get AI controlled mobs sending the correct
PlayerStates. (stunned, attacking, etc)
