Adds a table of contents in the markdown preview, with a button in the
header to toggle whether to show the TOC. When a user clicks one of the
TOC elements, the preview will scroll to the corresponding heading.
I've also cleaned up some MD preview styling that was inconsistent and
causing the preview to overflow unnecessarily. This also fixes some
terminology in the preview code.

This adjusts the block header styling to remove a bunch of unnecessary
attributes and to ensure that we have more consistent shrinking
behavior. Now, file paths will truncate starting on the left side, to
preserve the file name as long as possible. Also, the widget name can
shrink down to zero, while preserving the widget icon, since it's
unnecessary to have both when the widget is small.
