Improve output page formats

[jcranch]

We need to better utilise the metadata we have collected.

There are several things we have which we are not using at all:

• crossreferences in to each page
• crossreferences out of each page
• the original bailii URL

And there are probably prettier and better ways to display the things we are using.

Once we have nice indexing pages (an index for each court, etc), we can use the metadata to generate URLs to the appropriate page.

What we need, really, is an improved HTML template for the page.

I'll take a look, as I'm supposed to be doing the indexes anyway.
