Replaced all instances of Version14, Version15, Version20, Version30 and Version31 enums by type-safe equivalents.
Added gloverrides.xml to support overrides to function parameters / return types. This will make future spec updates easier to merge.
Improved handling of invalid tokens in the specs.
Bindings are now written in alphabetical order. This will reduce patch size for future updates and make side-by-side comparisons easier to perform.
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).
The doc processor can now document more OpenGL functions (e.g. GL.Color3).
Cleaned up several pieces of code in Bind (but I'm afraid it's hopeless - spaghetti code at its greatest).
Minor cleanup. Added code to turn ALL_CAPS enums into .Net CamelCase enums - must take care of the extensions before enabling this.
Added a couple new commandline options, and fixed a misspelling (NestedEnumsClass was NestedEunmsClass, ugh!)
Updated the ExampleLauncher to not process exceptions. Updated the IExample interface to contain the Launch method. Updated examples and the ExampleLauncher according to the IExample interface.
Synced with gl3 branch.
