(svn r15389) -Feature: Add ability to select which base graphics set is used from the Game Options window. The change takes effect when the window is closed. This option can only be used from the intro menu, as reloading graphics during a game may cause issues.

/**
* Makes class IDs unique to each GRF file.
* Houses can be assigned class IDs which are only comparable within the GRF
* file they were defined in. This mapping ensures that if two houses have the
* same class as defined by the GRF file, the classes are different within the
* game. An array of HouseClassMapping structs is created, and the array index
* of the struct that matches both the GRF ID and the class ID is the class ID
* used in the game.
*
* Although similar to the HouseIDMapping struct above, this serves a different
* purpose. Since the class ID is not saved anywhere, this mapping does not
* need to be persistent; it just needs to keep class ids unique.
