Making toLua use the package names?

[L-28C <kixdemp@...>]

Hello everyone!

Hey, I remember toLua used to give stuff like 'tolua_package_open(...)', 
but now it just gives out 'tolua__open(...)'...

I have multiple bindings, so of course that latter function will be 
defined more than once... :-/

What's the magic trick to get the former instead? Thanks!
