Exit with error on startup if using the wrong IWAD. Having multiple binaries can cause some confusion - some users try to run chocolate-doom with hexen.wad, thinking it is supported. Add a startup check that makes sure the user is not trying to start the game using the wrong IWAD file for the binary being run. This fixes #382.
