md5 -> isbn index

move all books in the library to an isbn index.

better still, use a single protocol handler to reference all kinds of
extensions to firefox.

i.e.  stuff://isbn/123...

these could then be replaced by somewhat helpful links for the
external view, and directly link to functionality in the internal

basic idea is that it's a pain to add protocol handlers or type
handlers to firefox, so to do it once for all types is maybe best.
