Raytracer Integration: Uses Engine's mouse, camera and keyboard.
Updating fRaytracer.glsl.
Raytracer Integration. Merging, rolling back some UVF stuff (Sorry Franck), moving UVF into a separate class and adding a UVF callback example. Removing compiler warnings. Added -Wno-long-long to Linux definitions because EXPRTK requires it. Added UVF to .pro file.
Merge branch 'master' of https://github.com/UMLComputerGraphics/GraphicsProject
Merging, again. Fixing segfault.
