Fix quest opcode mapping for WoW 3.3.5a

Browse source 
Corrected opcode assignments:
- 0x18F = SMSG_QUESTGIVER_QUEST_INVALID (not QUEST_COMPLETE)
- 0x191 = SMSG_QUESTGIVER_QUEST_COMPLETE

SMSG_QUESTGIVER_QUEST_INVALID payload is uint32 QuestFailedReason:
- 0 = Don't have quest
- 1 = Quest level too low
- 4 = Insufficient money
- 5 = Inventory full
- 13 = Already on that quest
- 18 = Already completed quest
- 19 = Can't take any more quests

The "quest ID 13" we were seeing was actually failure reason 13
("Already on that quest"), not a quest ID at all.
