(svn r2454) * Codechange: Move #include "stdafx.h" and "openttd.h" from rail.h to rail.c

Browse Source 
* Codechange: Move declaration of lookup arrays into the functions that need them. This doesn't pollute the global namespace with the array names.
* Add: rail.h to the openttd.vcproj and openttd.dsp for MSVC.
