review request - glbinding - new C++ bindings for OpenGL

[Ken Cunningham]

glbinding is a c++ binding for OpenGL that some OpenGL ports, eg widelands, are using for debugging at present and moving towards for general use.
this is the current version as of today.
appears to work without issues. All examples build and work correctly.

would be needed for the devel+debug version of widelands I have sitting in the dock, or if someone wanted to rebuild and debug the current widelands version.
