Core/Opcodes:

Added Structure for:
* CMSG_GAMEOBJECT_QUERY
* CMSG_GAMEOBJ_REPORT_USE
* CMSG_GAMEOBJ_USE
* SMSG_GAMEOBJECT_QUERY_RESPONSE

Got structure from WPP: https://github.com/TrinityCore/WowPacketParser/blob/master/WowPacketParserModule.V6_0_2_19033/Parsers/GameObjectHandler.cs#L20

Any feedback is welcome :)
