remove global.h header. Move global Cg context handle into NvShader? as a
static member. Move LoadCgSourceProgram? to NvShader?.cpp, but make shader
classes use the methods NvShader::loadVertex/FragmentProgram instead.
There are still some users of LoadCgSourceProgram? left that need the context
handle.
