Thompson theme: implement facet block view

Background

The Thompson HTML/CSS contains views which have not been implemented in the theme yet.

Requirements.

• Implement the "default" facet block view in block/facet

• Allow one facet item (per facet) at a time (no multiselect)

• Use "All" when nothing has been selected

• Ignore the date range facet, this currently cannot be inplemented in Integrated by default

• Add the number of items: (45) (might not be available with the "All" option)

Test scenarios

• Place a facet block, using the "default" view

• Does the facet work?

• Test with multiple facets

• Click all items in different order
