Second assignment for master's degree

It implements only the requirements until exercise 6: model rendering with textures and shading, with an interface that allows you to modify both model and shading parameters. Currently the shading is done with Phong, and the rendering is still not done on the interface window. The scene navigation has full mouse movement, with the ability to rotate around the model with Alt+left click, and look around with right click.

The release includes a model that is loaded at the beginning of the program.
