Simplifying audible messages

* Create the audible_message() proc to replace most instance of   " for(var/......mob/M in hearers(...)      show_message(..., 2)"
* Fixes a few cases of deaf people being able to hear audible messages.

* fixing typos and missing emotes in emote lists.
Gunhog is going to do these in botcall, no need to do it yourself.
