Normalize light names

[svrooij]

For better use i'm using spaces in my light names, but it might not be such a good idea to use that in the topic. hue/status/lights/Eettafel links

I'm using many topics with spaces, no pain for me. But if you want you can introduce a new command line param like e.g. --replace-spaces or smth.
