David G Yu 28f2574bc5 Moved GLEW dependencies to glLoader wrapper
This introduces an internal glLoader library which allows
most of the implementation to be agnostic about the
implementation of the GL loading library.  Specifically,
this removes references to the GLEW headers and libraries
from the rest of the source code and build system.
