Subject: Fix crash in Aura::Update. Check if target has Invisibility or
 Stealth aura before checking IsVisibleForOrDetect to allow cast spells on
 invisible triggers and fix pet linked spells. Send correct message to client
 if target is not visible for caster. Sorry for my previous buging commits.
