Services: only split messages on the HELP command and add empty lines for styling

I talked about the splitting with @ekimekim but I couldn't find it after the merge, so here it is. When a service just sends one line of text, splitting it every 80 characters looks kinda weird and doesn't make much sense. (Poking @ekimekim in this again to make sure he agrees with this :P). I also added some empty lines before and after listing the commands for better readability.
I think you meant something like `winMessage.split("\n")` (or, better: save `winMessage` as a list of lines) as this will output every character on each line and be bad, especially since one of the characters is `\n`.
