[core] Batch small changes

[oliviertassinari]

• [test] Stop using createRender 1492b7e: the helper is deprecated, time to stop using it.
• [docs] Fix render in dev mod in IE 11 0de54dd: for some reason, Babel is smarter and can detect the previous dodge syntax we used. We should be good with an eval. This was preventing us to investigate IE 11 issues in dev mod.
• [ROADMAP] Add Sparkline b58e281: it was already part of "Charts".
• [Ad] Include bonsaiilabs course 9e571cb: a preview
  
• [AppBar] Better handle print dfe75c6: This problem can be seen in https://bonsaiilabs.com/. The app bar is visible on every printed page. I think that it should only be in the first one.
  
• [Backdrop] Add a documentation page 540b5dd: I have used https://vuetifyjs.com/en/components/overlays as inspiration.
• [Autocomplete] Fix a small visual detail 3c653c8: I have spotted the issue on https://help.affilimate.io/ by @mlent
  
• [docs] Use the same background color as reactjs fcbd193: I have changed the code background color with the same one React is using in its documentation. It's slightly biased toward the blue: from #333333 to #272c34.
