Type: Object sound pointer, normal
Purpose: Plays the "bossit" sound effect at full volume.
Notes: In DOOM, this codepointer was also responsible for initializing the internal list of Boss Spawn Spot objects. If the number of objects was incorrect, this code pointer could crash the game. However, this behavior has been moved, as of BOOM, to an internal level init function, and the limit on spawn spots has also been removed.
