Reason for PR

OpenTK version 1.1.1589.5942 is causing a System.AccessViolationException on my machine.

This seems to be related to the older version of OpenGL required by OpenTK 1.1.1589

Upgrading to OpenTK version 1.1.2349.61993 fixes the issue but both the newer versions of OpenTK and OpenGL have made breaking changes to their respective APIs.

The few changes below update the RLNET API to be compatible with the API changes.
