Unecessary multiple database requests when determining the release type

To determine the release type the script first makes a database request to get the _GamePieceTypes,id_ and than inserts it in the sql script. It would be much more efficient if we just join the _GamePieceTypes_ table to the _MasterList_ and use the type name directly.

I already prepared a fix but I wanted to ask if it is okay if I also change the whole SQL to ISO/ANSI compliant joins?
