Fix Cheat Sheet for new MDI [skip ci]

[why]
Although commit
  69e8c0e  Add current Material Design Icons

claims that we updated the Cheat Sheet after adding the new Material
Design Icons, that actually did not happen.

[how]
Add new MDI's i_*.sh file to all. That is used by the generate-css that
also generates the cheat sheet web page.
