Fix text positioning bug with chat
fixed the floating room id bug, made the name/text inputs of chatbox clear on first click
moved chatbox to right side of canvas
turned off debug for updateModule, if you need debug statements, go to the console via firebug or chrome's built in console and type updateModule.debug = true
also put all debug statements for uiModule under an if(debug)
added code to detect system OS due to issue that appears only on Firefox on Ubuntu x86(maybe x64 too)
moved the upload image hidden div above the buttons which is better from a UI perspective
