Fix buttons appearing to be clickable when in the disabled state.
Submit buttons are normally disabled after a form is submitted. Before
these buttons would still look clickable. Now disabled buttons are greyed
out instead of looking the same as normal buttons.
Disable font boosting on mobile. By default, when desktop mode is
enabled on mobile, mobile browsers will automagically increase the size
of text. Usually they do so poorly, making things like headers smaller
than body text, which breaks the layout.

Remove all unnecessary rules from our CSS reset stylesheet.
Our CSS reset was based on a combination of Eric Meyer's CSS reset [1]
and Nicholas Gallagher's normalize.css [2]. Neither had been updated in
over 10 years, so they both contained a lot of unnecessary cruft. This
included workarounds for bugs in ancient versions of IE, and rules for
elements we don't use. Some of these rules had already been removed
upstream, but we never synchronized our copy of normalize.css with it.
This fixes some minor issues with vertical alignment of form inputs,
caused by unnecessary `vertical-align: middle` rules.
