Core/Logging:

- Implement sLog.outSQLDriver that will log SQL driver related events (non-content related).
- Queries will now be logged into this file as well instead of normal log file (requires debug build).
- Don´t forget to update your authserver.conf and worldserver.conf
Core/build:
- Fix non-PCH build
