Merge branch 'master' into staging_065

Conflicts were:
- README.md: Two commits targeted the brightness table. #781 from
14. April 2018 on master and #684 from 05. December 2017 on next.
- powerlevel9k.zsh-theme: Two commits targeted the rbenv segment. Both
achieve the same thing: To show the Ruby version number always. #795 on
next from 14. April 2018 and #610 on master from 28. September 2017. I
went with #795 here as this - although being newer - is the one on
master, and that should be more stable.
