Improved usability

The script saves now the device codes in the config and listens to pseudo codes consisting of the device number and the state.
Like 10 for the first device 1 and the state off 0. It also listens for other commands like restartwhich restarts the NodeMCU.
If the device gets an command which is unkown it logs help text with all codes and commands.
