SFW version

[JohannesNE]

I have realized that there are a few NSFW words in the diverse literature used in this project.
e.g

literature-clock/docs/times/00_05.json

Line 4 in bacedf1

"quote_first": "E.M. Security, normally so scrupulous with their fucking trucks at ",

I suggest using a URL parameter like ?sfw to trigger the SFW version.

Pull requests are very welcome :)
