Change 2 openGL declarations

Removed APPLE suffix from glGenVertexArrays and glBindVertexArray. 
Not sure what the difference is, however the unaltered declarations did not work, and changed declarations do.
System is Windows 8, 32 bit, translating http://www.opengl-tutorial.org/beginners-tutorials/tutorial-2-the-first-triangle/ into lua code.
Before: Blue screen, no triangle. 
After: Blue screen, red triangle.
