The following stealth changes are implemented.

 - Combat no longer removes stealth, only damage does
 - Creatures will pursue a stealthed unit they cannot see if they're already in combat with them
 - When a player is ~~3 yards~~ 8% + 1.5 yards away from the usual stealth detection distance, the creature will perform the "alerted" effect.
 - When sitting/sleeping creatures are distracted or alerted, they will stand up
 - Idle movement creatures will return to their original (spawn) orientation after distract/alert
 - When entering combat with a distracted/alerted creature, distract state is removed
 - NPC no longer have a limit to stealth visibility (granted by stealth modifier spells/buffs)
 - If alert visibility is greater than aggro range, no alert sent
