Core/QuestStatus:

- Separate rewarded quests from active quests, and store them in a new table to reduce database size
- Drop the no longer needed `rewarded` column from character_queststatus for smaller table size
- Prevent filling the database with dropped quests
  - Delete useless records
- Implement queststatus save "queues" instead of states
- Minor optimizations

WARNING: Backup your database!
