Style bibliographic items

[rbeezer]

A continuation of #4.

A bibliographic item has a number (which MBX or SL2X provides). Long-term this could be a string like "Jud1999" in "author-year" format. This should be styled in square brackets (provided by CSS or hard-coded). It should be positioned somewhat like a list label.

Then a long bit of text, about a sentence in length, with all the usual info. Let MBX or SL2X style this crudely for now, it is too complicated for CSS at this point in the project.

There can be an optional sequence of paragraphs that follow, for annotated bibliographies. It should be positioned so it looks associated with info above it (indented? fine tune vertical spacing?)

Can you suggest sample HTML we should produce, and then provide the styling? Example output now (which actually renders quite nicely!)
