Improve look of listviews for projects, texts, Q's

Instead of presenting projects, texts and questions as a table view
suitable for editing, we should present them in a view more like the
design of the spec.

There's quite a bit of fake data being presented here, like the number
of questions per text, unread answers, unread comments, and so on.
Eventually this will be turned into real API calls, but for now this
gives us a page to look at that closely resembles the real thing.
Make the fake data look subtly wrong

I decided to make all the numbers in the fake data negative. That way
they look almost-but-not-quite right, and once the real API calls are
written it will be obvious when the fake data is replaced by real data
because the numbers will start turning positive. (Or zero).
