// The first argument is the cheat code.
//
// The second argument is its DEH name, or NULL if it's not supported by -deh.
//
// The third argument is a combination of the bitmasks:
// {always, not_dm, not_coop, not_net, not_menu, not_demo, not_deh},
// which excludes the cheat during certain modes of play.
//
// The fourth argument is the handler function.
//
// The fifth argument is passed to the handler function if it's non-negative;
// if negative, then its negative indicates the number of extra characters
// expected after the cheat code, which are passed to the handler function
// via a pointer to a buffer (after folding any letters to lowercase).
