Initial Commit for GLEW

Note:  Libs not included in the commit (yet).  I prefer the libs be on
the path "GL/..." which means the libs just be ANYWHERE on any of your
system paths.  A common path is C:\Program Files (x86)\Microsoft
SDKs\Windows\v7.0A (or other version #)

Currently is statically compiled.
