Add support to custom shaders

[paulojamorim]

Currently, InVesalius has fixed scene lighting options. Shaders allow you to manipulate part of the graphics pipeline, being able, for example, to change the color, lighting and camera of the scene. In the medical field this is useful as some regions can be better highlighted just by changing the lighting.
