…dded version support defines to GLExtensions.hpp.
…3.2+ compatibility context as well. While the compatibility profile functionality is not 100% identical to the EXT/ARB functionality, the extent to which SFML makes use of geometry shaders should not pose any serious problems to a developer who is aware of the subtle differences. The current geometry shader example already requires GLSL 1.50 which was only available in OpenGL 3.2+. (Closes #1768)

Implements/Fixes #1768.
How do you test this? Well... the hardest part is getting a system that doesn't advertise ARB_geometry_shader4 although it supports OpenGL 3.2+. Then just run the geometry shader example and see if anything shows up on the screen.
