* HIGHLY EXPERIMENTAL - USE AT OWN RISK *

Database Layer:
- Implement connection pooling: Instead of 1 delay thread per database, you can configure between 1 and 32 worker threads that have a seperate thread in the core and have a seperate connection to the MySQL server (based on raczman/Albator´s database layer for Trinitycore3)
- Implement a configurable thread bundle for synchroneous requests from seperate core threads (see worldserver.conf.dist for more info)
- Every mapupdate thread now has its seperate MySQL connection to the world and characters database
- Drop inconsistent PExecuteLog function - query logging will be implemented CONSISTENTLY later
- Drop current prepared statement interface - this will be done *properly* later
- You´ll need to update your worldserver.conf and authserver.conf
- You´re recommended to make a backup of your databases before using this.
* HIGHLY EXPERIMENTAL - USE AT OWN RISK *
