Update Semantic-UI to 0.11.0 (from: bot)

This is an automated pull request by a bot.  It checks to see if Semantic-UI
has any new tags, and if it does, it prepares and sends a pull request.

If you have any issues with the bot please contact f.bagnardi@gmail.com 
[(@brigand)](https://github.com/brigand/), or [github support](https://github.com/contact) 
(if it's urgent).  GitHub has my full permission to disable the bot's account for any reason.

I don't forsee an issue with it, but code is known to be bug prone :-)
