Speech semaphore

The speech semaphore restricts talkers' ability to talk.

By default, there are two semaphores for NPC: friendlies & foes (based on IsPlayerAlly). See GetSpeechSemaphore in ai_speech.h

If UseSemaphore returns true, only one friendly and one foe is allowed to talk at a time.

If UseSemaphore returns false (whether based entirely on code or on spawnflags), the talker can interrupt other talkers.

Note:Any interrupted talkers will continue to talk.
