Core/DBLayer:

- Add basic prepared statement interface (without implementation and thus without testing, without resultset support).
- Based on raczman/Albator´s work on TrinityCore3

Build:
- Add sLog define ¨hack¨ in DatbaseWorkerPool.h to fix some more sLog errors temporarily

FYI: Builds on windows
