Photo model added.
Logbook parser now puts mugshots in as photo models, and descriptions from the old folk html pages in as "blurbs" on the person model.
Experimented with eye candy and a random logbook quote generator.
Also, the urls for the person model now allow lookups using their actual first and last name in the url instead of the primary key. We should do similar things for all models, maybe even using the url as a search which results in a page with multiple model instance results if the input is ambiguous (e.g. they only enter a first name).
