/* 
If you want to add a new option, do this:
First add the option to the TParam struct (game_config.h).

Then edit the below functions:

- LoadConfigFile. Use
	SPIntN for integer and boolean values
	SPStrN for strings.
	The first value is always 'line', the second defines the tag within the
	brackets [ ], and the last value is the default.
	
- SetConfigDefaults. These values are used as long as no options file exists.
	It's a good idea to use the same values as the defaults in LoadConfigFile.
	
- SaveConfigFile. See the other entries; it should be self-explanatory.
	If an options file exists, you will have to change any value at runtime
	on the configuration screen to overwrite the file. Then you will see the 
	new entry.
