Updating existing database with latest updates

If you are using one of the development branches of Mangos then you know there are often many database updates that can happen.

You can apply each of them by hand should you choose.
But you can use the InstallDatabases.bat script found in the database repo to do the work for you.

Run the script and you will see a screen like:

    __  __      _  _  ___  ___  ___
   |  \/  |__ _| \| |/ __|/ _ \/ __|   Database Setup and
   | |\/| / _` | .` | (_ | (_) \__ \
   |_|  |_\__,_|_|\_|\___|\___/|___/  World Loader v0.07
