*Implement Aura Type 247 (SPELL_AURA_CLONE_CASTER) and 279 (SPELL_AURA_INITIALIZE_IMAGES)

*Handle CMSG_GET_MIRRORIMAGE_DATA opcode.
*Save Minions follow angle to allow themmoving in a formation
*Improvements in SpellAI: correctly evade and select attack target for creatures without threat list
*Use SpellAI instead of PetAI for not controllable guardians
*Only guardians with SUMMON_TYPE_PET are controllable now
*Add script and template data for Mirror Image.
*Thanks to Drahy for help.
