d3dx9_36: Implements D3DXGetShaderVersion

["Luis C. Busquets Pérez"]

This functions gets the Version Token of a binary shader. This Token is 
the first of the binary stream so it is as easy as picling the pointed 
DWORD. This is all public information available to the public.

To implement a test would be far more complicated as it would mean to 
include a binary shader. Anyway, I have tested the results with Civ4 (by 
making a derivation on d3dx9_32 with this function and using the 
original d3dx9_36.D3DXGetShaderVersion function) and the results where 
the same for all the shaders that where present.
