Module creation & registration now made a lot simpler. In essence, each module file is now self-contained and only needs a NODEMCU_MODULE(MYNAME, "myname", myname_map, luaopen_myname); line to both be automatically recognised by the Lua initialization as well as honor the LUA_USE_MODULES_MYNAME #define.
