Conflicts were mostly due to the addition of body classes to the settings page,
this was caused by rejecting upstream changes for most of those files and
modifying Settings::BaseController instead.

Another cause of conflicts was the deletion of client-side checking of
display name / bio length, this was modified in app/javascript/core/settings.js
instead.
