Fixes #13202: Always use overflow: auto; on .table-responsive to prevent content breaking out of containers

Fixes #14095: Add basic styling for captions, which we've for some reason been missing all this time.

Fixes #13974, #14123: Remove translate3d repaint performance enhancement for text rendering and position wonkiness

Fixes #13953: Remove the progress bar min-width styles for low percentages to avoid jumping progress

Fixes #12738 again: use max-device-width instead of max-width for .navbar-collapse height in landscape devices

Now we are on par with what we have on the gh-pages dist/ folder.
