ofxWinTouchHook

windows 7 + 8 touch for OF

• using 'hooks' to catch touch events before the window processes the events
• no need to modify glfw/glu source with hooks
• tested on win7+8 with OF 0.9 with Visual Studio 2015
• added #define USE_WM_POINTER_EVENTS to ofxWinTouchHook.h to receive WM_POINTER events only (win8), comment out for WM_TOUCH
