build lua differently so that it has at least a prayer at interoperating with plug-in dlls. at least, it can load them. there may be other problems later due to the dlls generally being compiled against a different CRT (vc8) than our lua and luainterface (vc10). we could fix this if we needed to by compiling the CUSTOMIZED lua in vc8 and referencing it from the vc10 luainterface.
