LuaDll.luaL_register should add the null entry to the input array #1
Description
The native C luaL_register expects that the last entry in the array of luaL_Reg objets to contain a null name and func.
Instead of relying on the caller to do this, LuaDll.luaL_register should ensure that the last entry is null and, if not, ether copy the array into one that does contain a null final entry OR append the entry to it so the caller doesn't have to remember that step.
