Spelling mistake in --help text

[DJGoossens]

Thanks for the nifty utility. Mostly I just point it at https://justabigclock.com/false/night/en-US/analog/0. I noted a small error, easily fixed.

./webscreensaver --help

gives the following output:

usage: webscreensaver [-h] [-window-id WINDOW_ID] ... (etc)

  -cycle                Cycle to the next creensaver from the list

(etc)

'creensaver' should be 'screensaver'.

Cheerio
