The screenshots weren't doing much good without being embedded in the
text... and in fact, looking at them for I think the first time,
they're badly out of date with the app. So cut them.
We might add screenshots later, but on the other hand if we do a good
job with the forms themselves, they should be superfluous.
While it's sometimes nice to put a few selectors on the same line,
it is generally better to have a consistent way of formatting our
selectors, and most of our code up until now lists them vertically.
This change fixes the linter to enforce one selector per line, and
it cleans up the places in the CSS where we had multiple selectors
on the same line.
The advantages of one-per-line are as followers:
* cleaner diffs
* easier to see when multiple areas of the app may have the
same format
* less likely to go over 80 cols
* makes it more clear where we have deep nesting in the
individual selectors
* makes it easier for our linting tools to enforce
whitespace violations
This also fixed an old bug where we had ".landing_page h2, h4", which
sets "h4" styles outside of the landing page.
