[FIXED] Duplicate GL_RED

[ra4king]

GL11 and GL30 both have a GL_RED constant with the same value. This causes a conflict error when statically importing both classes. Fix is to simply remove GL_RED from GL30

Also, add a test case that *-imports all GLXX and extensions classes to test for duplicates.

This bug was found by theagentd and sproingie suggested the test case, so credit goes to them.

While it seems inconsistent to have constants/methods declared in GL30 which are already in GL10, removing the one from GL30 now would break existing application. I would defer that cleanup to LWJGL 3.0.

I believe this would only trivially break source code; the constants are otherwise inlined in to bytecode.

And let's face it, there's not a lot of LWJGL OpenGL3.0 code out there is there.

Thanks for the report, it's been removed.
