Merge pull request #11960 from MitchesD/hor

Scripts/HallsOfReflection: Major changes
DB/Gameobjects: Added some missing gameobjects spawns
DB: Changed WDBVerified startdard to VerifiedBuild
DB/Gameobjects: Fixed Gymer's cage phasemask to make it appear while doing "The Storm King's Vengeance" quest
Core/GameObject: Set trap type 0 back to GO_READY after activation.

Otherwise it would be activated again on every update. My fault, moving the activation code to GO_ACTIVATED skips the cooldown check.
