Horde3D

For those who don't check the wiki often i have added 3 tutorials on how to setup a opengl context and then init horde.
The three tutorials include sdl,qt,and gtkmm. Hope they can benefit some The hope is that they can help newbies setup horde and begin learning without worrying about how to creating the context.

Thanks a lot for that!
