This has an important implication: Previously the config was loaded before IWADINFO so in order to allow the config to access the data this had to be switched around. This means that zdoom.pk3 will not be looked for in the global IWAD search paths anymore, but since it shouldn't be there to begin with it should be an acceptable compromise.
