Icon canvases now have fixed width by default under FA7
(https://fontawesome.com…/changelog) and this was previously applied with
`fa-fw`. We should add `fa-width-auto` by default to our icons to
maintain the current styling we had under FA6, and remove the redundant
`fa-fw` class from the checklist plugin (which specifies classes outside
of the icon-library).
