Change Log:
* 2014-05-03: Started adding min-widths to prevent weird wraps in narrow windows.
* 2014-04-07: When viewing a todo list by itself, the list title (and optional comment for the entire list) no longer floats underneath the list commands (Edit, Delete..., Copy..., Move...).
* 2014-01-20: Worked on document editing iframe to fill width, but can't get inside the to modify its own CSS.
* 2013-11-11: Disabled the "printer feed holes" background image from the Basecamp announcements blog so it doesn't repeat at wider widths.
* 2013-10-29: Disabled the blue lines in text documents to work around the repeating vertical stripe.
* 2013-10-24: Fixed the right margin on posts you can edit so the Edit/Delete link floater doesn't cover the text of the first post.
* 2013-10-04: Added CSS to make the footer "who to contact" stuff when posting flexible.
* 2013-09-30: Added some new CSS to make Todo lists behave a little better. Project footer stuff now expands.

Issues:
* Project cards in the main Projects list will not grow to fill the width-- they are hard-coded to 3-per-row.
* Text document "previews" in a Project's main view will grow and shrink in width a bit before snapping to new rows.
* When viewing Todo Lists, it's possible for the righthand "sidebar" to overflow past the bottom of the white "page" background, if it is longer than the list itself.
* When editing Text Documents, the editable width does not grow and the horizontal "line rules" do not disappear, since we can't modify the CSS inside the <iframe>.
