Move to Bootstrap 4

Bootstrap < 4.1.2 has the following CVE:
https://nvd.nist.gov/vuln/detail/CVE-2018-14041

Removed bootstrap-theme.css due to "Replaced the separate optional
theme with configurable options via SCSS variables
(e.g., $enable-gradients: true)."

Added "width: 100%" to a few places where width 100% was no longer
getting inherited.
Moved a few elements and adjusted styles to get the same look as
before.

See https://getbootstrap.com/docs/4.0/migration/ for more
information.

Tested: Manually on a Witherspoon.
