Fully implemented SSAO and added tweakable parameters (controllable in NessieTestScene with the scroolwheel); changed the way models are loaded: all the components get flipped (and the faces' vertices are now rendered in the 'right' order); the 3d meshes no longer have screen-x flipped textures; implemented multiple materials per object with material groups; added a simple .mtl file loader; model files now have a set of default materials which get copied upon instantiation; added Handyman test model (ripped from Bioshock Infinite) with its textures (dds and png);
Removed leftover jpg textures and added heart normal map
