Simplifying audible messages

* Create the audible_message() proc to replace most instances of   " for(var/......mob/M in hearers(...)      show_message(..., 2)"
* Fixes a few cases of deaf people being able to hear audible messages.
* Adding a couple missed say().
* fixing typos and missing emotes in emote lists.
* Removes object_talk() proc.
* fixes not being able to hear audible messages when in a closet in the dark.
* Fixes #3782 
@Miauw62  The problem here is the get_dist(src, M) in the message. I'd need to rework the audible_message proc itself, just to be able to use it here.
