Merge branch 'dev' of https://github.com/asimo42/PuzzleAssembly into dev
Syntax fixes to TrackedPiece.cpp
SoundPlayer class added.
SoundEffectPlayer class added.
Able to include SoundEffectPlayer.h now and compile.

Runtracking.h to stdafx.h.

-Also added more sounds.
Added calling of CameraPrefs inside program.

-Changed playSoundEffect()

start, piece placed and game completed correctly.
