Replaced GLEW with (a highly customized) loader generated by glLoadGen, restructured GLExtensions.hpp for easier extension bookkeeping, make use of GLEXT definitions in Shader.cpp and Texture.cpp as well, replaced GL_MAX_TEXTURE_COORDS with GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS, implemented flags for requesting a debug or core/compatibility profile context, changed the default context version from 2.0 to 2.1.
