Fixed issue with multiple GLControls becoming invisible. Simplified GLControl, the platform dependent code now resides in GLContext and WindowInfo - GLControl itself is platform independent, just like GameWindow. This allowed to remove IGLControl.cs, WinGLControl.cs, X11GLControl.cs and DummyGLControl.cs
