consider enhancing with slide-show/presentation mode

[yarikoptic]

Currently present in _episodes materials are prepared largely for self-study/reading, not presentation style. We might like to enhance it so there are slides + details per each

Per @satra findings:

• http://swcarpentry.github.io/slideshows/creating-lesson/index.html#slide-20
• "we may be able to turn things into slide shows as well, better for presentation mode if you want to start at the beginning:" http://swcarpentry.github.io/slideshows/creating-lesson/index.html#slide-0

oops... I guess we had some commits with "Fixes" pointing to the older ohbm2018-training which closed this issue

@satra - did you try "it"? I am not sure if carpentries themselves use it any longer (here is my fresh question to them https://github.com/swcarpentry/slideshows/issues/33)
