new Lua 5.2.1 library bindings for Pascal

[Cybermonkey]

I used the bindings here: http://lua-users.org/files/wiki_insecure/lua52.pas
Anything wrong with them?

Oh, I didn't know that header existed. A few points are different, though :
- it lacks a few macros;
- it lets users initialize the library by themselves without providing a basic "initLua" function; actually I believe there is no choice possible on runtime as to which DLL/SO to use(library link is defined as "external LUA_LIB_NAME;");
- there's not the TLua manager class, that adds some degree of transparency when it comes to register functions within the interpreter.
