added voice samples for THE_CO
for each sound file, I created a class in description.ext
added two scripts that help to play the voice samples, including lip movement, while taking care of pitch, volume, and time acceleration; they also display the subtitles as sideChats
replaced all of THE_CO's sideChat()s with calls to unit[radio]speak.sqf, and replaced the sleep()s by a scriptDone()
some smaller changes pertaining to the recently added voice casting for THE_CO
changed the expActiv field of two triggers at krya nera; now uses calls to script files as opposed to editing the contents of a field in Arma's editor
