Added a file to handle the shaders to the project. Files are empty.
Added default shader programs. Set the project settings correctly to use glew, too.
Added text file reading method to the Shader class.
Added a class to load a Shader with the default OpenGL commands.
Filled the code with life when loading the shader. In addition comments were added to the ShaderLoader.h. The ShaderLoader is used by the shader.cpp program now.
Added the shader chain to the running program. Curently nothing happens. Maybe I need to add vertices which are rendered.
Fixed the gitingore file with a default one from github (for Visual Studio).
Include sdf file.
