Gameboard window is now drawn fullscreen in the right place.

-Also specified where windows are drawn during calibration so they aren't overlapping each other.
Took away wait for completion in play_Sound() so the program will now continue running as the sound is played.
Changed how a piece placed correctly is determined slightly.

-changed checkIfPlacedCorrectly() in while loop to getIfPlacedCorrectly()
-Other small hint tweeks.
Added globals class to Functions.h to hold level of difficulty.
Can now select difficulty from GUI to change types of hints you get.
Add pieces.clear() before adding new set of pieces.

Multiple copies of pieces were getting added to piece list everytime a new game was run.
