Clickable title, term highlighting, support for multi-valued fields.
Some adjustments required to get the demo to work again.
Made facet handling somewhat more robust.
Give selected facets (filters) their own class, and change the click() bindings for add_nav and del_nav.
Cleanup; added configurable number of snippets for highlighting; added ws-normalisation of text.
