Bootstrap 4.0 (not beta) with Sage 8.5

It looks like assets/styles/components/_grid.scss contains the only conflicts with upgrading from bootstrap#v4.0.0-alpha.4 to bootstrap#4.0 in Sage 8.5, but I’d love to get some confirmation on that from the Roots community.

Maybe I had installed an older version of Sage because 8.5.4 does have Bootstrap 4 (not alpha).

My repo had the alpha version. Then when I bower uninstall bootstrap and bower install #bootstrap4.0, bower stopped injecting bootstrap into main.scss.

Not sure why. Solution was to clone Sage 8.5.0 with composer and copy the changed files over.
