Created a method in VoiceRecognitionThread that allows other activities to pass a hashmap of commands and runnables to execute upon command.  This was implemented, tested, and verified using the MessageListActivity.  Also fixed the Start listening command bug.
Added voice commands to RobotListActivity, added sound effect when message is received, cosmetically patched null pointer exception on modifier.  Tested with two robot configs and worked well.  Multiple messages worked well also.  Keeps slowing down, could be due to Glass overheating.
