[NTG-context] Different versions of Lua and error in the same versions of ConTeXt (Fedora vs Win7)

The point is that Pablo Rodriguez use Fedora 20, which comes with Lua-5.2.2.

I think TeX Live 2014 uses Lua-5.2.3 on all platforms. I don't know differences between 5.2.2 and 5.2.3. Current windows version of standalone ConTeXt also uses 5.2.3. Best, Akira
