Adjusted file-extension-detection if-else block structure in 3rdparty/untz/src/UntzSound.cpp; added missing #include of threading/RScopedLock.h in src/moai-http-client/MOAIHttpTaskCurlThread.h.
Told moai-lib-http-client to recreate its PCH file.
Adjusted incorrect #include of Windows.h.
AKUSimContextInitialize seems to have been replaced by AKUInitializeSim.
Updated VS2012 project references to point to Box2D 2.3.0.
