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 
I mean, if I replace the for(...)+show_message(..) by just audible_message("... get_dist(src, M)..") then the "M" will be undefined.
