Lua has issues with functions returning references

[fodinabor]

As reported here: http://polycode.org/community/143-questions-of-a-new-user/p1#p560

The function we're talking of looks like this in C++: const String& getStringValue(const String& configNamespace, const String& key);

The conversion in Lua:

function Config:getStringValue(configNamespace, key)
    local retVal = Polycore.Config_getStringValue(self.__ptr, configNamespace, key)
    if retVal == nil then return nil end
    local __c = _G["String"]("__skip_ptr__")
    __c.__ptr = retVal
    return __c
end

But it still is no string we could work in Lua with.
