PipEngine Prototype file

This is very early version of PipEngine. What is: - Custom Renderables support and sample Mesh class, - Vectors and Matrixes classes, - Some goodies like Color class, Scene class etc., - Broken camera, to be fixed, - Not usable Logger. What is NOT: - Good math libary (sin, cos, tan functions), - Texture support. - Particles, skyboxes etc. This package contains also a sample model and sh***y PAMF exporter (My Python and Blender API knowledge is very, very bad, sorry). To compile you need SFML's and OpenGL's libaries. If you can write some needed code (TODO is in almost every header) or Python exporter, that support textures, we will be really grateful. We need you! :-)
