* Platform/X11/X11GLContext.cs: Modified BindingsBase to define
abstract GetAddress method (reason: removes OpenTK.Graphics-specific
code from BindingsBase and allows it to be used in different
bindings).
Implemented GraphicsBindingsBase and modified the OpenGL and OpenGL|ES
bindings to use this.
Modified the GLX bindings to inherit from BindingsBase (reason:
reduces code duplication for extension loading).
Removed OpenTK.Platform.Utilities.CreateWindowInfo and made the platform-specific CreateWindowInfo methods public (e.g. CreateX11WindowInfo).
Moved Mono Windows.Forms-specific code into X11GLControl.
Removed OpenTK.Platform.Utilities.IsIdle.
Removed obsolete methods from OpenTK.Platform.Utilities.
Marked OpenTK.Platform.Utilities.CreateGraphicsContext as obsolete (use GraphicsContext constructor instead).
Made IWindowInfo implementations private.

* Source/OpenTK/Platform/Dummy/DummyGLContext.cs: Added IsDisposed
property to IGraphicsContext and implemented in all context classes.
Removed 'bool disposed' fields from these classes in favor of the
new property.
Added GraphicsContextBase, which acts as the foundation of all IGraphicsContext implementations.
Added DesktopGraphicsContext, which acts as the foundation of all desktop (i.e. not ES) IGraphicsContext implementations.
Modified all IGraphicsContext implementations to inherit from GraphicsContextBase and/or DesktopGraphicsContext.
Removed OpenTK.Graphics.Glu class (reason: deprecated upstream; most functionality provided by OpenTK math; not compatible with OpenGL 3.0+.) OpenTK.Graphics.Glu can be accessed through OpenTK.Compatibility.
Added OpenGL|ES-specific ErrorHelper classes.
Moved OpenTK.Graphics.DisplayDevice and OpenTK.Graphics.DisplayResolution to the root OpenTK namespace (reason: their functionality is not specific and does not depend on OpenTK.Graphics).
Split Graphics*Exception classes into different files.
Made GraphicsErrorException public (reason: necessary for OpenTK.Compatibility).
Improved CreateDummyContext logic to detect and use the context handle of the current thread or a specified handle.
Removed GetCurrentContext() methods from platform-specific context implementations (everything now goes through the relevant IPlatformFactories).
Added GraphicsContext.ErrorChecking property to temporarily disable error checking if necessary.
Error checking is now added to all functions in debug mode (the generator would miss specific CLS-compliant overloads before).
