From 57b8571a8acd559b7a92c2d5ffbfe96b0c4b5b98 Mon Sep 17 00:00:00 2001
From: Monroe Linden <monroe@lindenlab.com>
Date: Fri, 24 Sep 2010 16:17:12 -0700
Subject: Added the VoiceDisableMic debug setting to completely disable the
 ability to open the mic.

Also hoisted PTT key handling from LLVivoxVoiceClient up to LLVoiceClient.  This cleans up LLVoiceModuleInterface a bit and makes the PTT logic more centralized.
